What is so wrong with ballistic fingerprinting Sure, I’ve heard the argument that gun barrels can be replaced or modified. As a parallel to actual fingerprinting, criminals sometimes wear gloves or alter their fingertips, but that doesn’t discourage us from collecting this kind of forensic evidence.

The ATF tracing initiative has consistently shown that less than 1 percent of gun dealers are linked to a majority of firearms recovered from criminal enterprises. While most of these traces may have involved legitimate transactions, ATF investigations have uncovered thousands of federal law violations by these dealers. Unfortunately, recent congressional legislation significantly limits public and law enforcement access to gun-tracing information, thereby shielding rogue dealers.

Aside from some paranoid view of government intrusion, what really is the danger of firearms registration or of background checks on all gun sales We register automobiles, and qualify and license drivers; why not do the same with guns and their owners It makes no sense to prevent law enforcement from tracking firearms transfers that fuel the illegal market. We could even install LoJack-style, GPS devices into new guns to curtail trade in stolen firearms.
