Actually, putting cops that get tagged with abuse reprimands in pink uniforms for 6 months would probably chill out their testosterone poisoning.
Well...I used to think that NYC at night was pretty dangerous...until I visited L.A.
My friends in the Newark, N.J. P.D. (see motorcyclists in an old Queen Latifa video, forgot name, for introduction to them) did astounding things with their recreational bikes....in an effort to "stay brave" ALL the time. In their job...if you thought about it, and were sane, you probably wouldn't report for work, especially at night. "Testosterone" properly managed, has saved many lives. It helps one to survive. Just ask commercial fishermen.
The late-night streets of parts of L.A. require a LOT of guts to patrol, and remember...one is wearing the "enemy uniform" too, and being rather conspicuous...not hiding....and deliberately entering already violent situations, among people who often don't mind losing all they have, including their lives, just to commit a public act of bravado. They are also often chemically altered beyond the point of any rationality or restraint. They don't just go down and give up when even mortally wounded. This is evidently why even with the new directives, officers are not completely refused "permission" to use whatever force and implement immediately available and necessary in order to go home alive.
