Comment: He didn't

(See in situ)


He didn't

appear to be acknowledging the officers at all.

We can't see what happened before the window smash so all we can do is speculate, but for probable cause an officer has to actually witness something that makes them suspect a crime may be (or has been) committed. If the officers are asking him to roll down the window, or otherwise try to engage him and he just ignores them then the officers can say based on that they had reasonable suspicion something was wrong. Once they have probable cause they can act.

If he cracked his window so he could hear officer instructions and acknowledge he could hear them and had no problem cooperating with what they needed to do short of violating his rights then the officers might not have proceeded as they did. This is speculation since we can't see what happened prior.
