Every gun that was picked in Mexico and that originated in the USA can be traced by serial number back to an American citizen’s driver’s license or SSN. THE BUYER WHO SOLD THE GUN TO THE NARCOTRAFFICANTES IS THE ONE WHO SHOULD BE INVESTIGATED IF ANYONE IS! If such a buyer is purchasing large numbers of arms for re-sale then he can be charged with firearms offenses.
“THE BUYER WHO SOLD THE GUN TO THE NARCOTRAFFICANTES IS THE ONE WHO SHOULD BE INVESTIGATED IF ANYONE IS!”
BINGO!
And if this isn’t being done, then why not?
