I did not mean to say that all guns should be banned because of the possibility that they might be stolen. But, I absolutely do think that the frequency with which they are stolen and then used to kill or injure someone is a factor that should go into how readily accessible they are and how they are regulated.
Florida law allows a person to have a weapon in their car as long as it is "securely encased," but the definition of that is so lax that basically having it in a zipped bag is good enough. As car burglars rifle through the console, they find it, can tell what it is, and take it. I have a real problem with that.
A possible solution is to treat a gun as a dangerous instrumentality that deserves a heightened degree of protection from theft such that, if a person has such a weapon in their car, and it is stolen, the person who had it in the car can be held civilly liable if the gun is then used to kill or injure someone. You'd see a lot less people buying such weapons if they didn't have a damn good reason to have one and, if they did buy one, they'd take "securely encased" to heart.
