There's a time and place to pick your battle. The time tested ending is those with the most guns win. If i knew the girl or boy who was in that situation my 1st response would be to remove them as fast as possible from that confrontation. My 2nd action should plan A fail would be to knock them out before they became a statistic. Having been in a situation or two over time, until one is actually in the deep end, arm chair quarter backing does or proves nothing.
The flip side is If I interfere / become engaged with said LE what's my course of action and what justifies my doing so. Being dead does nothing to resolve said scenario.
AS i have mentioned in class. Better to be a Live Witness than a Dead Hero. YMMV
So you continue with your train of thought, i'll stick with mine.
