The defendant:
Urged his followers to "fight like hell" and exhorted them to march to the Capitol.
A significant set of his followers proceeded to breach the security fences, attack security personnel, enter the Chamber, and put a halt to the proceedings.
Some of the followers were armed with firearms, chemical weapons, or other weapons.
One follower was killed while illegally entering the Chamber, and other persons (security and followers) were injured.
Some of the crowd vandalized offices and the Chamber.
During the mêlée, the defendant watched it on television and waited for hours to ask for a stop.
Some of the followers erected a gallows and displayed signs to "Hang Mike Pence", the Vice-President in charge of the proceedings.
During the next four years, many of these followers were convicted of various felonies in normal criminal courts.
Four years later, the defendant pardoned almost all of those convicted of these crimes.
A few of those pardoned quickly got back into trouble for unrelated crimes.
Nope, nothing to see here.
"Incitement to riot" is a federal crime. See 18 U.S. Code chapter 102 .
