In HK about 1 or 2 yrs ago.....a news article on the front page, and on the news channels...... there was a police speed trap using a multanova, with an officer sitting next to it and a roadblock on the opposite lane stopping traffic on the other side with laser.
Anyhow......one crazy guy sped through and got flashed, his photo taken. He got so angry, he drove back, stopped his car, stole the multanova and ran back into his car to drive off. The police fired one shot on his car, and the guy dropped the radar out his window while speeding away, completely damaging it. The radar's camera part was intact and police was able to get the car's license plate from it.....therefore they went to his house few hours later and arrested him.
