You were just linked to the elements for prosecuting treason. That IS under the rule of law.
On this issue, you will never be able to sever the Court of Public Opinion from the legal processes. The public’s perception exists and will take a life of its own. It is not ‘revenge’. It is anger directed at the lack of exactly what you mentioned ‘The Rule of Law’.
When a killer is caught for unspeakable crimes, the public is angry and may appear to want revenge because of the anger. But it is not so much ‘anger’ as it is ‘hurt’. Anger follows Hurt. Revenge is inflammation. Justice is the healing treatment or cure. The Public wants justice served. It is not ‘revenge’, it is justice.
These bad actors of the so-called Deep State are guilty as hell of treason. They have hurt America. The public is hurt, the public wants justice.
Revenge is a short-term process of venting emotion. Justice is a process of establishing and maintaining order. The former may overlap the latter, but the latter endures whereas the former wanes.
Revenge v. Justice; don’t conflate the two - not too much. Separate the processes. Treason is a term used in the Constitution. By definition, it is a part of the Rule of Law.
When the charges of Treason are broken down into specific crimes and civil violations, of which there will be dozens at least, the court’s orderly process of trial will be seen by the world as an example of American Rule of Law. The term ‘Treason’ will be the headline, the general descriptor of those trials.
Trump is interesting. He campaigned on revenge, then won, flipped and chose justice. Revenge gets votes, no doubt about it. Justice maintains the republic, at least for now.
President Trump does not help his legal cause by suggesting that Dems are treasonous because they did not clap during his SOTU address. How many times have Republicans not clapped during Dem SOTU addresses? It may play to the base, but is the kind of thing that can bite back. Unfortunately, I’m not sure he really cares about Republicans as a whole.
