IMO, the thing that caused the cops to react that way was when Hill rolled up his window and refused to lower it again.
The windows were tinted, and the cops could not see what he was doing inside the car, that raised the temperature level to boiling causing the cops to react.
The next time the cops face someone who rolls up their window and no one can see what they are doing, suppose they reach for a gun and shoot thru the window, suppose they pass something to the passenger to hide evidence, any number of reasons the cops were on edge when the window was rolled up.
Did they overreact, perhaps but they went home last night and so did Tyreek Hill.
IMO-—TINTED WINDOWS SHOULD BE OUTLAWED IN EVERY SINGLE STATE-—NO EXCEPTIONS.
