Regardless of what the law says, I believe that most on here abstain from imbibing while carrying. The risk is just not worth the enjoyment of your favorite alcoholic beverage.
Now that the Wisconsin law is settled, and the Virginia anti-drinking opinions are coming out, I guess I'll at least make sure to say there are plenty of members here who drink RESPONSIBLY while not being unarmed and defenseless.
I'm glad I live in a state that doesn't treat me like a child and only makes it illegal to carry when DRUNK. To specify, I mean NV, which is where I live most of the time. (It's also legal in UT, with a slightly lower BAC limit)
If I go to a bar and have a drink while watching a game with friends (adults know how many drinks they can have over what time period), I don't leave my gun at home or in the car. I also still keep my knife, and my car keys *horrors!* in my pocket, too.
Those who can't drink responsibly probably shouldn't drink at all.
Depending on local laws, being worried about prosecutors MAY be an issue in your area. Here, they only care if the bad guy was the bad guy and whether or not you are justified in the shooting. Still, I'd rather be educating a jury than my friend educating those who came to my funeral.
