It's all theory anyway
What anyone would, or would not do is merely theory in any of these discussions. You may well have great morals and good intentions, but the situation itself will determine the final outcome.
Also, there is a huge difference between dealing with drunks and dealing with all out crazy or drug induced individuals. In the experiences given, do you not consider the fact that the attacker is perhaps slower and not quite as centered due to the drinking? Were the officer's responses different from what would have been if the attack came faster and harder from a sober person? I would surmise so..... I would further surmise the damage to the attacker would be considerably more as well...
It's all theory until you're in the middle of it. Then of course, it's too late to worry about it!
