This is a silly statement if you stop and look a it. Of course "law abiding citizens" would not be carrying a gun illegally, as then they wouldn't be "law abiding citizens." What law abiding citizens would do is to apply for and get a permit to carry their firearm legally (pretty easy to do), thus maintaining their status as "law abiding citizens."
It's silly if you have OCD or such, but normal people would understand what I meant.
And no, it's not pretty easy to get a CCW in places such as Baltimore and all of Maryland. It's pretty much impossible unless you have political connections, etc.
