we cant carry at all in Maryland, We do have a permit, but listen to this, in MD self defense is none existant- keep that in mind! So the only way to get a concealed weapons permit is if your life has been threatened, and you are in danger. The threat must be reported to the police, and you need a witness.
If your life is in danger, and you are carrying a deadly weapon, and that threat becomes a active threat, what are you going to do? Hmm sounds like you are probably going to defend yourself? And then you will probably get charged with murder, or something like that. I hate my state!
