Where are the shoulder belts, and if they have not been taken out how is this vehicle legal?
You've said something that makes sense. The PD must have initiated the seat belt rule for a reason, since nobody anticipates problems anymore. Even with seatbelts, a jolt could cause an injury in that vehicle. The other thing is that the police were clearly dragging him to the vehicle. Should they have waited for an ambulance?
It just might be that the vehicle, in which one could easily be injured or injure oneself and the lack of attention to medical and psychological issues, is a real problem.
The perpetually angry community would save a lot more lives dealing with issues like that.
