I own a nice, well-used (by me), 12 gauge coach gun. No, I'm not an N.R.A. member...I read no gun magazines and belong to no gun clubs...I attend no gun shows and have no gun buddies.
Never shot up a theatre or school or mall...never used it in an illegal (or, as I see it, improper) way.
Not seein' why my ownership or use of this shotgun should be moderated or hobbled cuz other folks do bad things with their guns.
Also not seein' why I should have to self-report my ownership and use of this shotgun to any one.
Whole whack of busy bodies with too much time on their hands worrying about the (potential) weeds in another's garden, if you ask me.
And: Bob's question stands...when pressure cooker bombs (easy to make) were used at a Boston Marathon running, little was said about the bombs (again, easy to make...the parts are legal, the process of weaponizing easy)... the focus, rightfully, was on the bad guys. But, let some one use a gun in a bad way and the focus (lately, anyway) is on the gun and how some (new) law would keep such weapons out of the 'wrong' hands.
Thing is, lots of anti-gun (not anti-crime) folks deem simply wanting a gun as 'wrong' so, they say, "no guns for you, bad, maladjusted, person!". Such folks are on a kind of snipe hunt cuz guns (of any kind, and the associated ammo) ain't goin' nowhere.
My suggestion to folks in the U.S. who find the very notion of 'gun' deplorable: buck up and move on.
My suggestion to folks outside the U.S. who find the notion of 'gun' deplorable: stay home.
Understand: I get that we here in America have a problem (several actually), but Pandora's Armory done opened its doors ages back and all the evils are loose...confiscations will fail...strict controls will fail...look here
https://homemadeguns.wordpress.com/ people will make what they want if they can't buy it.
It is what it is and all the wailin' and criticism and good (and not-so-good) intentions aren't gonna do jack...all the proposed and enacted legislations to hobble and moderate and stymie aren't gonna do jack.
But, please, chase them rainbows.
