Carrying doesn’t do crap for self defense. The moment a crazy asshole pulls their gun at you and shoots you won’t even be able to comprehend the situation quick enough and get your own piece out of the holster.
The crazy asshole always wins as they shoot first (they are usually cowards on top, so you might just get shot in the back).
More guns just leads to more crazy assholes with guns, I feel much safer in European countries.
