ATF visits a home to notify owner that possession of binary triggers in now a felony. The only problem is the owner never purchased a binary trigger, they only looked at a Gunbroker page with the trigger.

Analyst Comment: ATF is now using search history to target gun owners. Its unclear if the ATF subpoenaed server logs from Gunbroker, has cooperation with Gunbroker, or obtained the information through other sources like partner agencies or by purchasing search record data from a private broker.
