Great thread, and the findings are worthy of consideration.
One of the more sobering realizations I take away is that in the area in which I live - in which crime is often conducted by (at least) two umbrella gangs, Nortenos and Surenos, quite frequently when crimes are reported in the press there are more than 2 armed adversaries.
Often 3, occasionally 4, is more the norm. Very seldom (unless its a case of domestic violence) do you hear about only one armed adversary. They tend to run in groups of however many can fit into one car.
Its sort of grim to realize that your surviving an armed encounter depends, at least in part, on the probability that one or more of the group will run away when the shooting starts.....
Treat everyone you meet with dignity and respect....but have a plan to kill them just in case.
