Seems almost certain that the police killed the poor UPS driver when looking at the videos, the amount of police gunfire could very well have been the reason for the motorist being killed.
All around fucked up situation, but the police did move very recklessly in on the vehicle once it hit the traffic block, just a massive un-coordinated barrage of gunfire in dense traffic. Cops should have stayed their distance once the robbers opened fire on them and planned ahead while following on the helicopter.
No doubt the robbers caused all this, but the police response didn't seem to have helped anything, now some dude doing his job and someone driving somewhere is dead because of it. I'm curious if the cops even knew the UPS driver was being held hostage, or they just assumed everyone in the van was a target.
And as usual the police will not be found to have done anything wrong because they can do no wrong in the US since they are the law.
