Hill issued two dictates to the officer:
1) Don't tap on my window.
2) Don't tell me to roll down my window.
I don't know the specifics of the law in Florida, but Hill clearly had a deep window tint that didn't permit viewing inside the vehicle. I'd bet a substantial # of people would agree there was an implied threat in instructing the officer not to tap on the window. If the officer plausibly perceived those factors as a safety concern, would they not be justified in securing the scene, and would it not be Hill's behavior that had necessitated such escalation?
