The International Association of Chiefs of Police says guns confiscated from criminals by law enforcement agencies should be destroyed because putting them back in circulation "increases the availability of firearms which could be used again to kill or injure additional police officers and citizens." Also, federal agencies must destroy seized firearms unless they are needed as evidence or being used by the agency.
On the other side of the debate, some law enforcement officials say the selling of guns raises money to purchase crime-fighting equipment, and if the practice were abandoned, people would just buy weapons somewhere else. In fact, a growing number of states from Arizona to North Carolina are passing laws prohibiting agencies from destroying guns.
