You're right about the other agencies, but I thought that they used some 'alleged drug' excuse, along with 'illegal weapons' in order to get the original search warrants and used drug laws & DEA rules to justify their position. If so, then DEA would have been at least superficially or indirectly involved.
I haven't looked at those records since GWB took office. Some of the facts are kinda hazy now, but I can't forget what happened there.
What does GOLF have to do with GUNS?
No the DEA wasn't involved.
The claims of "drug" manufacturing & distribution was floated to get Gov. Ann Richards to allow the BATF to use TNG Helicopters.
Without the "drugs" nexus, the Posse Comitatus act would prohibit using assets military for domestic law enforcement.
