An official from the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives said this week mistakes were made during an undercover sting operation in Milwaukee and changes would be made in how future stings are run. A Journal Sentinel investigation revealed problems in a 10-month ATF sting an agents guns, including a machine gun, being stolen; the loss of an ATF ballistic shield; the theft of nearly $40,000 in merchandise from the sting storefront; careless handling of a sensitive operational plan; and the charging of the wrong suspects. The ATFs machine gun has not been recovered, a Milwaukee police spokesman said Thursday.
