Loopholes that kill—Literally

Over 50 percent of guns found at crime scenes are traced to only 1 percent of gun dealers. This reveals two important facts:
Most gun dealers are honest and obey federal and state laws and would decline a profitable sale if they were aware of illegality. 

Fortunately, for the 1 percent of unscrupulous and dishonest gun dealers, the ATF, because of the Tiahrt amendment, cannot make public the records of gun dealers whose guns end up at crime scenes, nor can they arrest the seller whose sales were “legal.” Moreover, in those infrequent cases where the ATF closes down a licensed dealer for infractions of the law, he/she can sell the business to a family member or trusted employee and through a change of “legal ownership” continue to operate the business.—America and Its Guns: A Theological Expose, page
