Again, show where a waiting period would have prevented any of these mass shootings.
If the insane are the 'low hanging fruit' of my argument, 'mass shootings' take that role in yours. Someone comes into a gun store/gun show and absolutely positively NEEDS that gun RIGHT NOW and you couldn't deign to suspect some problem in the making? Are all gun deaths a result of mass shootings, or are you willing to accept a plague of gun violence on our streets as nothing more than the cost of your 'freedom' to buy a gun with no background checks at all?
I am not opposed to "thorough background checks"....we already have them in place. Of course, no matter how "thorough", there will always be flaws in any system.
Again, I will type this slowly so you can read it.
We already have background checks !!
I have urgently bought a gun before. Twice. The first time I found a gun shop that was having a terrific sale on Glock 40' with tritium sites (and those big scary 13 round mags), and the sale was ending that day. The second time was when I was taking a new person deer hunting for the first time and needed to buy an extra rifle that day. Waiting periods are stupid and don't work. We have huge computer networks. The ATF should do their jobs and have a list of prohibited persons on the cloud where gun store owners can immediately access and check.
Your reference to a "plague of gun violence on the streets" is, again, ridiculous. Most street gun violence is done by criminals with illegally attained weapons. NO GUN LAW YOU COULD EVER DREAM UP (short of complete banning of all weapons by anyone) will solve this problem simply because these people operate completely outside the law.
