I don't understand the original point or question . Isn't what she was doing illegal ? Why is there something else that needs to be done about it ? Now "we" are acting like the anti's , just pass more laws , that will stop it
The OP gives the case, and then asks "what to do?"
He then mentions a registry and a "one gun a month" limit and why he's not in favor of either.
I'm not in favor of either, either, but neither is something to be considered as "something to do" about this case.
The only thing "to do" is see that this woman, and everyone else involved is prosecuted to the fullest extent of the law.
There is no need, and no reason to do anything else.
This is NOT a case of "tragedy would have been prevented by one more law..." if indeed there ever is actually such a thing...
It was brought up how laws don't actually prevent anything, and that is partially true. They do, and they don't.
No words on paper ever actually prevent anything. Only people choosing to obey them due to a certainty of punishment does. And that, is an unquantifiable thing. No one can give you any numbers on how many crimes were never committed.
Remove the general certainty of punishment (or even getting caught) and people don't fear the consequences of breaking the law. Big laws or little ones, the principle applies.
