>The precedent has been set in the U.S. If you can whip up an army of fanatics to assault the Capitol then you may do so with impunity.

No it has not. The people involved are being prosecuted and criminal punishments are being handed down.

Trump is not being prosecuted, because disagreeing with the official election results are not a crime, nor is it illegal to hold campaigns arguing your case. If Trump had actually done something illegal, he would be prosecuted.
