oh wait, that was local government. So how about the anti-war movement in the late 1960s, closer, but not much closer.
Before I go further though I start to wonder about your requirements, I mean from where I'm sitting it is a 'commonly' understood thing that the anti-war movements in the U.S are often targeted for investigation and attack by government agents, but for every commonly understood thing there are people that do not agree for some reason that the thing that is the common understanding of the situation is correct.
So - before continuing - what is your position on the Chicago 7 (https://en.wikipedia.org/wiki/Chicago_Seven)? Was there a conspiracy by the American government there or not? If there was then I have given an example even though not so far after McCarthyism was done, but more importantly if we can agree that there was then it is pretty easy to keep coming with examples over the years. If your opinion was there was not - but McCarthyism I take it was a bad thing in your book - what aspects of McCarthyism is needed to make an example you would find acceptable but would leave the Chicago 7 out?
on edit: of course my point with the Move bombing is that local government also counts in the U.S, although I suspect you would disagree otherwise there's lots of cops killing citizens and taking their property all over the country for you to choose from.
Didn't we already rule out the 1960's? That type of political violence really doesn't exist here anymore. Your perception of the country notwithstanding.
What is your position on Aaron Schwartz then?
Also, public forfeiture laws are not terrorism - they are policy.
