Of course it is a serious matter, to us, we are the people who want to own guns! To the rest of the people it hardly matters, and they are constantly told how they will be better off, and safer with fewer guns and gun owners.
I agree the anti's are pushing hard to get as many people as possible classified as prohibited, each one who is, is a victory for them, both in the real world, and in the political fantasy world they inhabit.
Since it is virtually impossible to legally get off the prohibited list, once on it, these individual "victories" for the anti's are essentially permanent.
Each person they get on the prohibited list is one more "mass killer that isn't going to get a gun". Each one prohibited "makes us all safer", etc., etc.
Personally, I'm not very worried about the guy who slapped his wife 40 years ago, pled to a minor DV charge, got a small fine, and has lived a normal life ever since. He's not the guy who typically becomes a rampage killer. It is both a tragedy and a travesty that Lautenberg makes him a prohibited person.
The social misfit, the mental child in an adult body, raised on violent TV and video games, given totally unrealistic expectations, taught the world "owes it to him", one who has never been involved with either the legal or mental health care system (no official background to check), THAT is the ticking time bomb I would be concerned about.
And none of our existing or proposed laws can do anything about them. NOR SHOULD THEY! One should not be a criminal, until one commits a crime.
However, it appears the anti's would rather restrict (they convict us in their own minds) everyone BEFORE the fact, rather than effectively punish the criminal after the crime. The whole concept seems rather bass-ackwards to me.
