In my last entry here (found below this one for those who don’t come here regularly) I made a point: if we’re going to have mad dog killers shoot up bars because they’re sure they won’t draw return fire there, it would be an awfully good idea if one or more of the good guys and gals in the bar were carrying and not drinking alcohol, and could shoot back. “Designated defenders,” as it were.
Greg Ellifritz is a friend whose great expertise as a self-defense instructor I can endorse. He has this to add to the topic on his own excellent blog, which I read regularly and think you would get a lot out of, too: http://www.activeresponsetraining.net/should-cops-carry-guns-off-duty-while-drinking-alcohol.
Obviously, no one is endorsing drunks with guns. But even if a change of law was necessary to allow sober carry in bars in some states, it makes sense to have someone in place at the scene equipped to stop the next person who wants to be on an every-five-minute tape-loop on CNN before he racks up a toll of tragedy like the last one in Thousand Oaks, or the worse one not so long ago in Orlando. A badge is not necessary. A gun in a rescuing hand is necessary.
