>> female Florida trooper’s screeching rant ...
High speed chases = high stress = adrenalin dump. Even you would screech.
And when she found out she was confronting a peer, there was need to maintain the professional demeanor.
Actually not. I'd stack close quarter combat and danger close fire support against any car chase. Leaders shout, but don't screech. Screeching doesn't lead or inspire; it just grates on frayed nerves and contributes to chaos. This female trooper's voice doesn't make one want to comply with her commands -- except perhaps to make her shut up. If anything, her screeching only elevates the danger of a violent confrontation.
