The problem (as I see it) is creeping incrementalism...
Any of you fine folks remember what the law was before 1968? Do you care? Should you care?
Before 68, there were no prohibitied persons. There were also no Federal age limits on purchase of firearms. Also no Federal license for firearms dealers (it was a state matter, the same as any other business).
A convicted felon, released after serving all their time, could legally buy a gun.
Mail order sales, with delivery to your home were not just legal, but common.
And did we have nuts going on shooting rampages back then, like we do today? I don't recall such. One might just think something other than the ability to buy a gun might be at work here....
One of the reasons against a mandatory universal background check is the oft demonstrated creeping incrementalism. First, its is felons, and the adjudicated insane who are prohibited. Fine. Ok. Now, it is also anyone with a domestice violence misdemeanor. Ever. Even if it was decades before the law was passed. What's next? Late payment on a bill? or worse, non payment? Clearly this demonstrates you are not a responsible individual, and therefore, cannot be trusted to own a gun!
Give them an inch and they will take a mile, no matter how long it takes them to convice enough of us that it is needed? ITs not just a slogan, it is a proven fact. Lawdog's cake story is very apt. We give ground, over, and over, and they never stop demending more.
Leaving aside the arguments about how well the system will work, or even how it could be implemented, any requirement for everyone to go though a mandatory check is simplya bad idea, in practice, if not in theory. But it sounds soo good!
This, of course assumes that there is no other means for people to get guns, and assumes that no one will slip through the cracks, and assumes that the imposition of this on us is a worthwhile and useful thing. Lots of assumptions there....
We are being conditioned to accept that we must prove ourselves innocent each and every time....already we see this principle being used in other areas of our lives, how long do you think it will be before a cash strapped govt siezes your bank account and demands you "proove" you didn't get that money dealing drugs? OR firearms? or whatever else they want to demonize?
Never happen? so you say, today.
Motorcycle helmets and seat belts are good ideas. But the govt mandating them isn't. It is only an excuse for them to pick your pocket because you chose a socially unacceptable risk. Note that YOU are not responsible if you get injured, society is, society has to pay the cost. That's their argument, and some time ago, they won that particular argument.
I'd like to remind all that the Bill of Rights does NOT grant us anything, it is a list of restrictions on what the govt may do, concerning SOME of our rights. We have a lot of "natural rights" that are not covered, and the BOR specifically says so.
background checks are not a restriction of 2nd Amendment rights per se, they are a restriction on your right to do as you see fit with your personal property, which just happens to be a gun. Gun ownership is a civil right.
We are not being judged on the content of our character, we are being judged on the fact that we wish to have firearms. That single fact makes our character suspect to the anti-gun crowd. We have to proove our character (by way of nothing prohibited on a background check) each and every time? How is that NOT a presumption of guilt?
