1:15:05 The assault vehicle is destroyed. This is an M8 Greyhound adjusted for the police. Normally the crew is 4, but 2 of those are for guns that are not on this version, so we will assume there are 2 cops inside.

2:02:43 Hans falls
2:05:39 Karl is shot
Total: 23
This kill count is pretty close, it just missed one of the guys in the chopper. This is understandable because at the time of the explosion, that is all you see, but in the scenes leading up to it, you see another passenger.
Body Count has the same count as the previous kill count and makes the same counting error in the helicopter.
