BATF got their ass handed to them on a platter by the Branch Davidians on their first encounter. They only lost the battle when the US Military aided the ATF, FBI et al in assaulting the compound with tanks and setting it on fire, killing dozens of children, women and men needlessly.
So, the President’s men will duly designate the next bunch of gun nuts as terrorists, and BATF can just drone-strike them.
Problem solved.
I disagree with the word "needlessly." The FBI needed to kill everyone and then burn the buildings to destroy any evidence that contradicted the government's version of what happened.
