What's with police cursing at people they're trying to apprehend? [View all]

So many of the videos we've seen show police screaming and cursing at the people they ended up shooting.

I could understand if they felt they had to yell to be heard, but cursing at them is an and indication of anger and complete lack of control.

No other public servant - or anyone else who serves the public - is given a pass for treating people with such anger, disrespect and outright abuse. But it's even worse when the people charged with keeping the peace and given the power of life and death and extraordinary discretion and often a pass when they choose death do so with such an obvious lack of control and abusiveness.

And no, don't tell me it's because they are in stressful situations and are only human. I don't want or expect the people with the badges and the guns to be able to fall back on the "Jeez! I can't be expected to control myself under stress."

Why aren't more questions raised about that?
