So I do have to push back on this. Yes, most folks were unarmed. But there were armed members of that crowd, and Trump knew it.
Mace, stun guns, baseball bats, etc. Pipe bombs. There's also recorded police radio that they had spotted people with AK-15s and Glocks. People faced weapons charges from that day. Guns were allegedly confiscated. 100 police officers were injured and 5 people died.
And more to the point- not only was Trump repeatedly informed before the event that there was a high likelihood of violence,
but he was also told during the event that people in the crowd were armed (which is why they were standing outside of the metal detectors). Trump said apparently said he didn't care because they weren't going to hurt him. He wanted the metal detectors removed so they would come closer to the stage. People who were there testified about this under oath.
He sent them to the Capitol building and told them that this was their last chance to save their country. They were there because of Trump, he organized an entire event to make them angry, and then he knowingly sent armed people to the Capitol. He literally told them to "Fight Like Hell". Did he tell them to bring weapons? No. Did he know they already had them? Yes.
And to be clear, Trump waited 3 hours to tell people to go home. Multiple people have testified under oath that people were pleading with him the whole time to call it off. And he refused. Even when he did finally do it, he told him he loved them and that they were special people and repeated all the same lies and lines that got them worked up to begin with. i.e. He justified their actions.
And two hours later he tweeted this:
I'm not going to call you disingenuous because I don't think that's your goal at all, but I am going to say that you are missing A LOT of information.
