You attack the US Capitol while in session there damn well better be terrorism enhancement.
Only for the planners, not the sheeple mob of red hatters. If they committed violence, there's charges for that, but terrorism implies premeditation.
Planning to protest in DC isn't terrorism. If it was, then I'm guilty of terrorism for being at the 2010 Restore Sanity Rally. Terrorism should be dealt with the same vigor as removing a black widow spider from a sleeping child's pillow. Drawing a conservative* line between protest and terrorism is not good for the First Amendment.
The premeditation to attack the Capitol in itself is a clear black and white line between unruly protest and terrorism.
*meaning too much power for the state. The Tories.
