If the NRA is willing to sponsor a program like this one, I fail to see why they'd be protesting a gun buyback program in Tucson
The NRA doesn't sponsor video buybacks either. If they did, they'd be stupid. If someone did this trick in my neck of the woods, I'd do exactly what other posters suggested:
* Go to WalMart, GameStop, etc. and clean the $5 bin out.
* Get my $25 gift certificate for each.
Gun buyback programs accomplish three goals:
1: They allow criminals to destroy evidence by safely ditching a "hot" gun.
2: They allow people to get above-retail value for broken or low-value firearms worth significantly less value than the turn-in amount.
3: Sucker owners of $200+ firearms into getting a feel-good coupon.
Numbers 1 and 3 are inherently immoral. The first destroys chains of evidence, because you can't prove that the defendant ever used a certain gun. If done outside the color of the law, people would be going to jail as "accessories after the fact".
Number 3 is theft as well: most people who turn guns in at gun buybacks are poor, and they could use the full value (usually $200 to $1000, or more) of the gun for their regular budget. Instead, they are convinced to take a token so that others feel good.
Number 2 is theft if public money is used too. Private citizens come in, selling crap and getting $100 back, money taken from their fellow citizens. To take the Tuscon buyback as an example: a woman tried to sell four rifles, but got no takers. I've sold into this environment; gun stores in Kentucky were buying .303 Enfields (in very poor, but working, shape) for $75 a year ago (now that same gun would be $125 wholesale, at least). If she couldn't walk into a gun store and get $50 each, then those rifles were complete crap, and Tuscon got ripped off.
Buybacks are worthless. Look at LA: the chief of police out there keeps trotting out the same plastic "rocket launcher" trainers and clean AK-47s (sorry, no criminal EVER touched those guns) after every buyback. If he really showed what they got, it's be boxes of broken Davis autoloaders, rusted top-break .32 revolvers, and single-shot shotguns that have bounced around in the back of a pickup since the 40s. All a city gets is boxes of scrap metal, criminals with cash to buy their next gun, and citizens who get the shaft.
As for fighting the Tucson buyback: State law says abandoned and surplus property has to be auctioned. The guns were turned over to the state: they're either abandoned or surplus. Why in the world should a citizen expect the state to do what the law says?
