ATF storefront had little to deter burglars

MILWAUKEE (AP) - A Milwaukee storefront that the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives used as part of an undercover sting operation had little security in place to ward of burglars.
    
The Milwaukee Journal Sentinel reports that new documents show the burglars had been to Fearless Distributing before to sell guns and drugs to undercover agents. When they robbed the place in October, they had such easy access that they propped a door open and returned the next day with a moving truck.
    
A bipartisan group in Congress wants the ATF to provide some answers. The ATF has launched an internal investigation.
    
Former federal prosecutor Rory Little says undercover operations can have great benefits, but there is also great risk. He says it all comes down to details and supervision.
