That's the point of concealed carry though, they don't know you're carrying, thus you have the element of surprise. And yes, while many muggings don't end in bloodshed there are those exceptions. Those are the reasons people carry, they don't want to be that exception. You're also trained to actually give in to their requests unless they demonstrate harm on you or another person. Basically, give them the money, but if they stick around, then you shoot them. I see your point in stating that a gun will enrage the person wishing you harm, but keep in mind that they aren't necessarily looking for a fight. They won't attack you if they know you're carrying. However, there are the exceptions that take a stance towards you and follow you waiting for your gun to be out of reach. This is another reason people concealed carry.Some_weirdGuy said:They're less likely to shoot someone who is unarmed, as their main motivation is to shoot you before you shoot them. If you aren't a threat then they're far more likely to take the money and run, rather than make it worse for them self by needlessly murdering someone.
Yes, there are exceptions, but if they're like that they're going to shoot you first weather you have a gun or not.
It's almost always safe to carry a firearm, unless of course you're on federal ground in which case it will be illegal.
