Every Friday afternoon the ATF sends out press releases from its 25 Field Divisions – big cities like Los Angeles, Miami, New York and 22 more. Users have to sign up to receive the emails, which usually describe the arrests the ATF claims it made during the week.
By far the vast majority of the actions described in the press releases – the arrests and the investigations – were not the result of any work by the ATF. The arrests were made by local cops who found a stolen gun or noticed that their suspect was a convicted felon and should not have possessed a firearm.
