Having a CCW doesn't protect you in any of those situations either. I KNOW you aren't making a case for banning guns altogether, but don't assume that your common street thug is anywhere near as smart as you are.
In general, drunks and shoulder thumpers will go elsewhere at the slightest sign of resistance. They aren't smart enough to set ambushes.
Those that are are the rare types of psychopaths, like the DC shooters, who will kill you no matter how you are carrying. Exactly the types of people we need to be armed against.
Over the past year, there have been innumerable stories posted here of people who CC and are jumped and need to use their firearm.
I have not seen even a single example of that for people who OC.
The “tactical advantage” that people talk of with CC is a myth, like the Yeti.
