Wow,do you mean that I have a 1st amendment right to invade the US Congress when it doesn't go the way I demand it does? Thanks for that clarification. Don't know about you, but if I were to entice a group to do that in my own name then I wouldn't see sunlight for at least 20 years.
But when we do it, we'll just tell them you said it was okay.
Is that what you think? A quick scenario here: You and your neighbor are talking over the fence. You tell him you need money so badly you are almost ready to rob a bank. So your neighbor actually does rob a bank to give you the money you need. Who do the police arrest, you or your neighbor?
The first amendment guarantees our right to free speech whether government likes that speech or not. Unless you can find the actual words Trump used to incite this riot, then there is no case. You can't blame Trump for how people reacted to what he said.
Furthermore we have several bits of evidence that whatever Trump said had nothing to do with the riot. The pipe bombs were planted well before that day or Trump's speech. The FBI warned the Capital police of a riot possibility the day before, and they came armed with zip lock handcuffs. This was not a spontaneous reaction to a speech, this was planned well ahead of time.
So now that it's been established that Trump's speech had nothing to do with the riot, what they actually impeached him on was exercising his first amendment rights.
