Dumble. I am not trying to start a geopolitical discussion on the merits or faults for drinking and OC just have a couple of questions/statements no directed towards you just your post.
In PA, it's not illegal to drink and carry or go to a bar and carry. It's also not illegal to be drunk and armed. For example, if I decided to drink a gallon of Maker's Mark, and stumble down the street while peeing my pants and carrying a gun, I'd be charged with drunk and disorderly, public intoxication, and maybe disorderly conduct. The firearm wouldn't be taken into account, at all, and wouldn't raise the misdemeanor to a felony offense. I'd be disarmed, taken to the drunk tank, and I'd have my gun returned when I soberedf up and was released. As it should be.
If a person gets in this shape should they be carrying a gun? Probably not. What good is it? Would they even recognize the threat or could they even hit it if they had to? Alcohol has the tendency to make folks 10 feet tall and buletproof add a firearm to the mix and it may lead to problems.
I would hope that someone who takes carrying a firearm seriously, as you do, would refrain from activities like you described as you do. Has there ever been a problem with guns in bars and intoxicated carriers? I am not egging things on I really don't know.
