Please tell me you did not just refer to a Semi-auto as a machine gun. I hope the mg part of that was refering to something else.
I agree with the health care part, it needs to be factored in.
As for why the mom NEEDS it, well, she was obviously cleared to own it when she bought it legally. Until it becomes illegal to buy something, who is to declare who needs what? I really like beer, I am legal to buy it, but I don't really NEED it. Well, some days I do.
The whole thing needs to be in the responsibity of ownership, no matter what we are talking about, cars boats planes, beer, guns.
