The assailant with the AK had absolutely no cover and probably didn't care if he hit the officers or not. He just wanted the cops to return fire. He could've done much more damage if he tried and protected himself.
if he was intent on killing those officers he could have easily done it. this looks to be suicide by cop. like i said, it sounds like he is screaming "kill me" in the video.
The female officer lost a finger. The shooter had books on how to dispose of dead bodies and how to build bombs in his vehicle.
You can tell the sound of a weapon based on the recording on a crappy police dash cam coming through your laptop speakers? Impressive
I could be wrong, but bet it isn't an AK-47. The hard part isn't the distorted sound but three people shooting all within seconds.
