There's already constitutional processes in place for removing offending parties from the executive and legislative branches
You mean the one where politicians decide if they're going to hold other politicians accountable? Yeah, that works as well as the bullshit that is Internal Affairs where the police decide if they're going to charge themselves with a crime.
No, what would be cool is if when the supreme court rules a law unconstitutional, they should also file contempt of court charges against the politicians who passed it, and they should be impeached, then removed from office and made to pay a fine. There you go, all nice and legal like, without firing a shot.
That would be great if SCOTUS wasn't part of the same corrupt system. However, even with your solution, it still involves police / military coming with guns to remove people from office.
