The Buffalo attack has given new life to a Democratic bill establishing domestic counterterrorism offices within DHS, DOJ and the FBI. The ACLU and others no longer oppose it.
Seems like a valid question: "No one had a satisfactory answer for me when I asked them why not simply call for the reporting provisions and reject the new domestic-terrorism offices. " Given the amount of bad-faith abuse of existing terrorism authorities, maybe we should think twice before expanding those authorities domestically. As you write, Madison Cawthorn and Dark MAGA have very different ideas of what constitutes 'terrorism' compared to the far left. Neither end of the spectrum should be trusted not to abuse domestic terrorism authorities to target those with whom they disagree.
So is doing nothing better?
For that matter, maybe the first question is will it pass in the Senate? Will Schumer even bring it to a vote before November?
