For years, there has been a peaceful transition of power between Presidents in the US. January 6 was the first time this tradition ended. Make no mistake, Jan 6 was a coup attempt, or more specifically, an autogolpe attempt. While power was ultimately transferred peacefully on Jan 20, Jan 6 was a coordinated effort to keep Trump in power, lead by Trump himself. If you don't believe this, then go back and watch all the Jan 6 Committee testimony and judge for yourself.
The fact that Jan 6 failed is of no consequence. Most coup attempts fail, and in the last 100 years, there have been hundreds of coup attempts, with only a few successes. But who gets things right the first time? In history, there are also examples of leaders who failed the first time in a coup attempt, but later assumed power. For example, Hitler, who failed in the Beer Hall Putsch, and Mussolini, who failed in the March on Rome. Those who do not learn from history are doomed to repeat it. And those that understand this know Trump cannot be allowed to attempt a second coup attempt.
Since Jan 6, there have been over 960 people charged with a crime. The ringleaders should not be allowed to get off scot free. And Trump was in the middle of it all.
