All you needed to do is sign a form saying you could legally own the gun and email a copy of your drivers license. That and $700 and the used glock with night plus 2 mags are all yours!
My guess is if you've committed to shooting people with guns, I doubt the crime of falsifying your identity is really going to deter you from buying said guns.
The other thing odd I found about the listing is that the gun is a used police gun. How can a gun formerly issued to a cop be this easily put out on the open market?
