TD- are you really comfortable with a situation, where I can go to a gun store in Nevada, and buy 50 handguns?
how is such a reality a good thing?
all gun sales aren't reported to the ATF or some other federal agency???
that's part of the problem. the ATF or whomever, should have records of how many guns a gun-dealer buys..and how many guns he sells. whenever something goes out of wack, they should get an immediate red-flag, and investigate.
I can't believe we don't have a national tracking system, so that every gun sale from manufacturer...to gun dealer...to gun buyer..is immediately tracked. how else are we gonna know if there is a crooked gun-dealer? he is gonna announce to the ATF that he is selling 50 handguns a pop to guys he thinks is selling them on the street to thugs?
why would be endanger his profit margin?

I have a suggestion-learn what the federal gun laws are before spouting off on this subject
every gun made in the USA or imported has to be logged in by the maker or the importer. when the weapon is sold to a dealer or a wholesaler, again it has to be recorded. when it is sold to a private individual, that individual fills out a form 4473 when the person buys it and that is retained by the dealership.
each FFL holder is subject to scheduled and random inspections. the ATF knows what guns that dealership received. if those guns are not properly recorded by the dealer the dealer will lose his license and may well be indicted
I'm speaking hypothetically, of course.
personally, I think its a very bad thing, that I can move to New Mexico, buy 50 Glocks all at once at one dealer, and then drive my car to Chicago and sell the guns on the street to local pushers & thieves.
sure..its illegal to sell guns to pushers & thieves. but that ain't gonna stop folks. relying on the better angels of criminals is a poor philosophy.
and crooked gun-dealers, who think they may be selling mass-loads of firearms to criminals, ain't gonna cut into their profit margin by contacting the ATF.

read this for example-I know this guy

this is all well and good, but it should be on computer. the ATF should be able to simply access the program, type in "Joe's Guns", see their wholesale & retail transactions, compare to their tax-returns, and make sure all is well. they shouldn't even have to visit the dealer to see if things are Kosher.
im shocked that in 2012, we don't have a nationwide computerized system, to track all gun sales in the USA...sending red-flags to the ATF when **** ain't right.
but again, if we limited personal gun purchases to say.....5 guns a month..that might make such a system actually work.
