By appointing FBI Director Kash Patel as acting head of the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), President Donald Trump took a step towards reining in a federal agency justifiably viewed by many as a threat to self-defense rights. He also signaled that he may consolidate government bodies that overlap in their responsibilities. It's impossible to credibly argue that the ATF doesn't need a shakeup. After all, this is a federal agency that ran guns to criminal gangs in Mexico as part of a bizarre and failed "investigation," manipulated mentally disabled people into participating in sting operations"and then arrested them, lost thousands of guns and gun parts, killed people over paperwork violations, and unilaterally reinterpreted laws to create new felonies out of thin air (which means more cause for sketchy investigations and stings). The federal police agency obsessively focused on firearms has long seemed determined to guarantee itself work by finding ever more things to police. But what about putting the same person in charge of both the ATF and the FBI? Merging agencies"if that's where this is headed"might improve internal communications by clarifying chains of command and eliminating interagency competition. But"and this is a big concern"done wrong, you'd end up with a supercharged federal enforcement agency with all the hostility to civil liberties its old components embodied when separate, but now with lots more clout.
