"They discussed and planned what was originally to be a peaceful protest"
Do your really believe that? Isn't that what groups like BLM say too?
The thing is when you get 100's of upset people together that are wanting to protest or make a stand to try to stop something...it never ends peaceful. Most if not every riot started out as a peaceful protest and every person knew it could or would escalate and didn't care. They thought it would make them heard better.
It's not a matter of what I believe. If it was planned, then who specifically planned it? What was their plan? Did they put anything in writing? Did they have maps of the Capitol? Did they have any schedules as to where key conspirators would be and what their assignments were? Was everybody in on it?
Most of those who have already pleaded guilty seem to be using the "Trump made me do it" defense, which isn't going to get them off the hook. But it does tend to put it back on Trump, which might prompt the question: What did Trump know and when did he know it? Did he plan it and organize it? If so, then that might explain why it turned out to be such a botch.
