The sales were captured on undercover video by private detectives working for Mayor Bloomberg's crusade against illegal guns. The detectives went to the Crossroads of the West gun show in Phoenix on Jan. 23 to expose the deadly loopholes in America's gun background check system.
The investigators bought Sig Sauer and Smith & Wesson 9-mm semiautomatics with high-capacity magazines, even after telling the gun dealers they "probably couldn't pass" a background check. Gun shows are exempt from background checks,
but vendors can't legally sell to anyone they think is prohibited from buying them.
