I honestly believe a majority of J6 participants were legitimate angry protestors who fell easy prey to an organized minority with a more advanced agenda. There was obviously a lot of mob mentality at work; most folks inside the Capitol looked more giddy than violent, like they couldn't believe the whole thing was happening. Many weren't bright to begin with and no doubt figured the "leaders" who were literally leading them into the Capitol had an end game in mind. Meanwhile, enjoy the anarchy, take pictures in Nancy Pelosi's office, s#!t on the floor if you gotta pinch one -- you are in the midst of something truly historic!
When you envision Donald Trump - your President - ready to sweep in on your heels, take over the Senate Chamber, and reclaim the Presidency, you probably do convince yourself you're on the right side of law and order.
So of course it's nuanced. And I think a prosecution strategy that takes into account the difference between dimwitted cattle and the people who happily position themselves as violence provoking leaders is appropriate.
