The speed of the BMW accident is to be identified.

　　Nanjing traffic police responded to nine doubts. The suspects are not rich second generation and official second generation.

　　In view of the traffic accident at the intersection of Shiyang Road and Youyi River in Qinhuai District on June 20th, Weibo, the official of Nanjing Traffic Management Bureau, released the latest investigation progress at 9: 00 last night. This is also the third briefing issued by the department, which responded to many doubts that have attracted wide attention.

　　1. How can the police determine that the arrested suspected man is the perpetrator?

　　The police extracted the blood on the airbag of the BMW car at the scene, and compared it with the blood sample of the suspected man captured by the police, and found it to be the same. Witnesses at the scene identified the arrested man as the suspect. In addition, the suspect Wang Jijin was hit by a vehicle airbag on his chest and was strangled by a seat belt, so it was determined that Wang Jijin was the driver of the BMW.

　　2. How does the police rule out the suspicion that the suspect was driving under the influence of drugs?

　　According to the police investigation, the suspect Wang Jijin had no drug abuse record. After the incident, he was tested for urine, and the result was negative, confirming that he was suspected of driving without drugs. During the on-site investigation, the police found that there was a bag of white powder on the ground about 30 meters away from the BMW. After being extracted and tested by the police, the white powder was starch, which ruled out the possibility of drugs.

　　3. How do the police rule out the suspicion of drunk driving?

　　After the incident, the police extracted the blood sample of the suspect and sent it for inspection. The identification result was that no ethanol component was detected in the blood sample of the suspect Wang Jijin.

　　4. It is understood that the BMW involved in the accident is a seizure car. Can the car be driven on the road, modified or insured?

　　After investigation, the license plate number of the BMW is Shaanxi AH8N88, the vehicle registration place is dmv, the traffic police detachment of Xi ‘an Public Security Bureau, and the owner is Xu Moumou. The initial registration date is March 13, 2014, and the inspection period is valid until March 31, 2016. At the end of 2014, the car was seized by Xi ‘an Public Security Bureau according to law. According to the relevant laws and regulations, the vehicle shall not be changed or transferred during the seizure period, but it does not affect the use of the vehicle. Appraised by the police, the car is a BMW "730" sedan, only the logo has been changed to the BMW "740" logo, and its appearance and technical parameters are consistent with the vehicle registration data. The car is insured with compulsory insurance and third party liability insurance in Pacific Insurance Company, and the insurance is valid from January 14, 2015 to January 13, 2016.

　　5. Is the BMW owned by the suspect and the source of the vehicle?

　　The registered owner of Shaanxi AH8N88 BMW is Xu Moumou, and the actual user is Wang Jijin. After investigation, due to debt disputes, the owner of the car changed hands several times to pay off debts. Later, Wang Jijin bought and used it privately at the price of 400,000 yuan in early 2015, but did not go through the relevant transfer procedures. At present, the police are investigating the multiple transactions of the car.

　　6. Is the suspect’s driver’s license within the validity period?

　　After investigation, Wang Jijin’s quasi-driving model is A2, and the driving license is valid from March 16, 2011 to March 16, 2021, with a validity period of 10 years.

　　7. Is the suspect a rich second generation or an official second generation?

　　After investigation, the suspect Wang Jijin (male, 35 years old, from Jingjiang, Jiangsu) temporarily lives in Jiangning District, Nanjing, and his parents are currently working in Jingjiang’s hometown. His father worked in Nanjing in 1992, and then operated the sales business of hydropower materials in a decorative city. In 2006, due to physical reasons, he handed over the shop to his son Wang Jijin. His mother has no job.

　　8. Why was the suspect wearing a helmet and restrained when he was examined by the police station?

　　The suspect Wang Jijin was very excited after being arrested and taken to the police station. He shouted loudly, hit his head against the wall and tried to bite the police and secret service personnel. For safety reasons, the police put on a helmet for Wang Jijin, handcuffed his hands behind his back and controlled his legs with restraint belts.

　　9. What is the speed of BMW? Is it speeding?

　　According to the video and eyewitness reports, the instantaneous speed of the BMW car was very fast, but the specific value needs further identification.

　　Jinghua Times News (Reporter Nie Hui)

Little mongla in Myanmar, which is adjacent to Menghai County in Xishuangbanna Dai Autonomous Prefecture, Yunnan Province, is known as "Little Las Vegas" and has great attraction to gamblers.

On March 16th, the upstream journalist learned from the People’s Procuratorate of Wujiang District, Suzhou City, Jiangsu Province that recently, a woman in Suzhou City, Yu Mou, was sentenced for the crime of crossing the border illegally. From September 2016 to June 2020, the woman used forged documents, smuggling and other means to cross the border 66 times.

Yu has repeatedly crossed the border by smuggling. All the pictures in this article are upstream news pictures.

Yu, a 45-year-old woman, is a self-employed person in Wujiang. In 2015, when chatting with friends, Yu learned that there were many casinos in Xiaomengla, Myanmar. A friend suggested that you can fly from Shanghai or Hangzhou to the border between Yunnan and North Myanmar, and the other party will have a special person to pick up and drop off. After entering North Myanmar by crossing the border illegally, special people will be arranged to pick them up, and the round-trip air tickets are free.

Soon after, Yu Mou and his friends and a group of people took a variety of means of transportation, and arrived at Little mongla through the roundabout mountain road at the border of Daluo Town in Xishuangbanna.

Zhang Neng, deputy director of the First Procuratorial Department of Wujiang District Procuratorate, said that in 2016, Yu met his gambling friend Wang when he participated in gambling in Myanmar. Considering the risk of smuggling by mountain road, with Wang’s help, Yu defrauded the entry and exit permit to participate in gambling activities in northern Myanmar four times by fictional employee identity and related materials of a trading company in Xishuangbanna. Each pass is valid for one year.

For cross-border gambling, Yu forged his identity and defrauded the entry and exit pass.

"The so-called alternative planting project is actually because poppy was originally planted in Myanmar, and the local government encourages farmers or other relevant agricultural employees to stop planting opium and replace the project of planting other cash crops. In fact, Yu himself has no knowledge of this project and knows nothing about it. He completely forged such a reason and defrauded the entry and exit documents. " Zhang neng introduced.

Around the end of 2020, Suzhou police found the clue that Yu had stolen the country (border) during the investigation of entry-exit related work. After investigation, from September 2016 to June 2020, Yu Mou crossed the border between China and Myanmar from Daluo Port and Mangxin Port in Yunnan for a total of 66 times and went to Little mongla for gambling. Yu was sentenced to four months’ criminal detention and fined 3000 yuan for the crime of crossing the country (border).

Yu claimed to be engaged in the alternative planting industry, but actually he didn’t understand the industry.

Upstream journalists learned that in 2021, Wujiang District People’s Procuratorate handled 8 cases of crossing the country (border), and 29 suspects were all suspected of cross-border gambling. According to Yu’s confession, there are "gunmen" in the hotels where he lived during overseas gambling. At the same time, after the gambler lost all his funds, the criminals will take the opportunity to lend usury and drain the gamblers completely before calling his family. Ask for the so-called ransom.

"According to the parties concerned, after arriving in northern Myanmar, they were illegally detained by local illegal personnel and gangs, and some of them were still held in water dungeons. When he was rescued, the skin of his two calves had festered. If the police are not rescued in time, personal safety may not be guaranteed. " Zhang neng said.

Upstream journalists have learned that in many cases of cross-border gambling by sneaking across the country (border), criminals usually attract and attract domestic gamblers to gamble abroad by providing free entry and exit services, free round-trip air tickets, accommodation and tourism.

Zhang Neng introduced that many suspects who sneaked across the border to participate in cross-border gambling have a subjective misunderstanding. They think that it is not illegal to participate in gambling abroad. And no matter which way, as long as the entry and exit documents are handled, it is not an act of stealing across the country (border). From a legal point of view, defrauding entry and exit documents and holding such documents to enter or leave the country also constitutes the crime of stealing the border.

　　There are some old products that may have faded out of people’s sight, but every time we think about them, we are full of memories. As a nostalgic column of GeekChoice, Geek Museum hopes to find these products that once surprised and moved us, and bring you back their charming qualities. Leica is one of the most influential camera brands in history.

　　In 1913, Oskar Barnack made the first prototype of Leica camera, which was also the first camera in the world with 35mm film. After several improvements, Leica I (Model A) was officially launched at the German Trade Fair in Leipzig in 1925.

　　In the next 100 years, Leica introduced countless classic cameras and lenses, and even more classic photos were recorded by photographers using Leica cameras. The portraits of Che Guevara, the kiss on Victory Day, Marilyn Monroe’s smile, Einstein’s tongue sticking out and other well-known photos were all taken with Leica cameras.

　　The history of Leica cameras may not be finished in several books, but this issue of Geek Museum wants to share with you the first digital camera in Leica’s most classic M series-Leica M8 released in 2006.

　　For a camera, 12 years is an out-and-out "old age", but from the appearance, Leica M8 has not left many traces of years.

　　Simple design, classic silver and black colors, the familiar "Coke logo", and the body made of magnesium alloy (metal frame) and brass (top box and bottom box) make Leica M8 look classic enough to look good in 2018.

　　Equally classic is the control of Leica M.

　　There are only two buttons on the front of Leica M8. On the left side of the lens is the lens release button, and on the right side is the wireframe lever. You can view the viewing range of lenses with different focal lengths in the viewfinder without changing the lens.

　　At the top, from right to left, there are a switch, a shutter speed pulsator, hot shoes and a small screen that can display the remaining number of SD cards and battery power. However, it may be that our M8 battery is a little aging, and the power display is not accurate. It is not significant to display the remaining number of SD cards for the SD cards that are now tens of hundreds of GB. Leica simply cut off this small screen in the later products.

　　With the pulsator on the right switch, users can directly choose three shooting modes, namely, S (single shot), C (continuous shot) or countdown, but the continuous shooting mode of Leica M8 is basically unavailable, its continuous shooting speed is only 2 shots per second, and it is very easy to crash in continuous shooting. After the crash, it can only be solved by removing the bottom cover and pulling out the battery.

　　Turning to the back of the camera, you can see a 2.5-inch screen that was still mainstream in 2006, but now it can be described as "garbage". Looking back at the photos taken with this screen for the first time is likely to make you doubt your life.

　　There are several buttons with clear functions on the left and right sides of the screen. A pulsator is integrated under the direction keys on the right side of the screen, which can improve the operation efficiency when browsing and enlarging scenes such as photos. On the upper left of the back is an optical viewfinder with automatic parallax compensation and magnification of 0.68.

　　When you turn to the bottom, you can see a knob. After removing the cover at the bottom, you can replace the SD card and battery. This 1900 mAh, 3.7V battery can theoretically provide very good endurance performance, but the actual performance depends on the aging degree of the battery itself and the external temperature.

　　Compared with Canon and Nikon digital SLR in the same period, the function of Leica M8 is much simpler. On the one hand, this is related to Leica’s design concept. Leica hopes that users can focus on shooting instead of spending time studying various complicated functions. On the other hand, this is also related to the focusing method adopted by Leica M8.

　　Auto-focus is an important indicator to evaluate the performance of the camera. Canon’s top-level high-speed SLR 1 DX Mark II is equipped with 41 cross-focus points, which is even more exaggerated in the era of no reversal. Fuji X-T3 is equipped with 425 phase detection points, and Sony’s high-speed sports machine A9 has 693 phase detection points.

　　Leica M is the other extreme. From the first Leica M released in 1954 to the recent M10 and M10-P, Leica M has always adopted a paraxial design with the view frame and the optical path of the shooting lens independent, without any autofocus capability, and can only use manual focusing.

　　When shooting, you can see a small translucent square in the middle of the optical viewfinder. When it is out of focus, the picture in the square is ghosted. Twist the focus ring of the camera to make the two pictures overlap, thus completing the focus. This focusing method is usually called "macular focus".

　　Photographers have also come up with many good ways to improve the focusing efficiency. For example, in hyperfocal distance, by using a wide-angle lens and a small aperture, the depth of field can be as large as possible, so that clear photos can be taken without focusing (similar to the front camera of a mobile phone). After mastering it skillfully, Leica M can be turned into a "street sweeping" artifact.

　　Compared with SLR in the same period, Leica M8′ s macular focusing has some special advantages. For example, when the shutter is pressed, the optical viewfinder will not be as black as SLR, and the surrounding environment can be better observed when shooting. The structure of manual focusing lens is simpler, so it is more convenient to make a small lens with excellent optical quality.

　　However, there are some inherent defects in macular focusing, for example, it is impossible to shoot at a macro (unless some new models are connected with a macro adapter to focus with LiveView), it is difficult to focus with a telephoto lens over 90mm (the wireframe of the viewfinder will be very small), and the accuracy is limited. It is not easy to focus with a large aperture lens such as Noctilux-M50 mm f/0.95 when the aperture is fully open and the depth of field is very shallow.

　　For "novices" who have never been exposed to paraxial cameras before and are used to modern SLR, reflex-free and smart phones, macular focusing still has a high learning cost, but in the eyes of many professional photographers, this "primitive" focusing method is an important part of Leica M’s unique experience.

　　Leica M8 uses a CCD made by Kodak, with 10.3 million pixels, and the size is APS-H, which is slightly larger than APC-C now, and the conversion ratio is 1.33. The Minolta M-Rokkor 40/2 hung on our M8 can just get the equivalent focal length of about 50 mm. On the M9 released in 2009, Leica upgraded the sensor to Quan Huafu, which made the M8 generation the only "defective pair" in Leica M history.

　　In order to get better picture quality, Leica also removed the infrared filter in front of the CCD on M8, and eliminated the moire fringe through the software processing of the camera. However, this design was later proved to be unreliable. Leica M8 has a high probability of making black objects purple in the sun. The solution is to install a UVIR filter in front of the lens. Leica has also given free UVIR filters to users who buy M8.

　　Leica M8 also has a very advanced mechanical shutter with the fastest speed of 1/8000th second at that time, and it can also shoot with a larger aperture in the sun to get better blur effect.

　　However, this high-speed shutter also caused the shutter sound of M8 to be loud, almost catching up with the SLR of the same period. The "elegance" of the paraxial camera was instantly halved with a "thud", which attracted the dissatisfaction of many photographers at that time. On M8.2, an upgraded version of M8 released two years later, Leica greatly reduced the shutter sound, but the shutter speed was also increased from 1/8000th of a second to 1/4000th of a second.

　　Considering that M8 is Leica’s first digital attempt on the M series, these minor problems are understandable. Fortunately, these small "bugs" did not affect the reputation of Leica M8 in image quality.

　　Today, there are still many fans and photographers who have a special liking for the color presented by the CCD of Leica’s first generation digital M, and even the graininess under high ISO has become a tool for many photographers to take black-and-white photos.

　　This is also the core reason why Leica M8 is still regarded as a classic by many users even though the product itself is not perfect. After all, technology will always beat time, but charming colors are the eternal pursuit of photographers.

　　Today, 12 years later, Leica M8 is still active in the second-hand camera trading forum at a price of about 10,000 yuan, becoming the first Leica M in the hands of many young photographers, and continues to play its unique value in this era dominated by smart phones and Quan Huafu mirrorless cameras.
