There is nothing to rebut. If you’re drunk and failing to stop for the cops, you’re at fault regardless of what happens, in regards traffic collisions.
*However*, this does not give the cops the right to shoot an unarmed suspect to death after the pursuit was over, with the suspect not even in a vehicle.
Looked like the guy was not going anywhere very fast, or was in any shape to be a grave threat to one of the heroic ossifers going home that night.
Target practice, heck yeah, why not, he can't shoot back?
