The ATF isn't part of the TSA. TSA is under the Department of Homeland Security and ATF is under the Department of Treasury. There were some movements with the U.S. Customs service merging with the U.S. Border Patrol. The Coast Guard was moved into the Department of Homeland Security.

I do worry about the TSA wanting to extend their reach into other parts of transportation. The Director of the TSA was in Pueblo awhile ago inspecting some railroad issues and was quoted as saying he would like the TSA to take over responsibility of the railroad security. I would not support that or any other movement to give TSA more responsibility or more power. TSA needs to be dismantled and the airport security turned back over to the airports and airlines.
