Havent read the whole thread, but this is wrong. The glass on police cars can withstand 9mm bullets at best. The rounds from something like an AK47 (7.62) wouldnt have a problem going through the glass, armour of a stanard police car.
I wonder if SF will eat their words now? It was only a couple weeks ago Hugh Orde said that it wouldnt be long until a police officer was killed and got completely clated by SF for it....
