Hitlers 1st try at overthrowing the German government wasn't 1933, it was 1923.
Castros 1st attempt at overthrowing Cuba wasn't 1958, it was 1952.
In pretty much any other country on earth when you lead a coup, there would have already been executions. The idea that somehow everything is ok because the people who died weren't the right politicians is absurd. History tells us that someone who is willing to lead a violent uprising once, is perfectly willing to do it again and again. They are perfectly willing to sabotage the people and the government to win power.
The absolute minimum that should be happening right now are massive and very public investigations by this government with the intent of jailing anyone found to have participated in any form in this coup attempt. The President should be charged and tried for his crimes against the American government to render him politically neutered at a minimum, jailed at best. This was treason, and not some protest gone wrong. This was an attempt to over throw a dully elected government of the United States of America.
