ALBANY, N.Y. (AP) - Most guns recovered from New York crimes last year originated in states with fewer legal restrictions, though the largest single source remains New York itself, where 1,595 were first purchased, federal data show. The Bureau of Alcohol, Tobacco, Firearms and Explosives - which traced 8,793 guns from New York crimes or investigations - reported that many came from southern or Eastern Seaboard states, though some originated in recorded retail sales from nearly every other state. ATF officials say the report shows that New York's restrictive gun laws have made it a "market state" for guns from elsewhere at a time when recent shootings have reignited the national debate on regulations. Authorities said the main weapon used in the killing of a dozen moviegoers in Aurora, Colo., was an AR-15 rifle modified with a high-capacity magazine that allowed firing many bullets without reloading. That gun would be illegal in New York.
