OK. So it affects how someone could respond to a situation. But again, that does not explain or prevent situations where a cop may have to use deadly force.
Yes it does........
All that I have already mentioned, plus best body armour and strict rules about wearing it (it gets hot!) plus exact procedures..... do help.
Then, when an op has to use deadly force she (or he) can show that she approached it right, communicated right, reacted right, warned (if poss) right etc etc....... and acted 'right' beyond any doubts. Recent very sad incidents have not been able to show this, which has caused civil commotion, etc...... all very sad.
