Treason is a tough issue to approach.
Certainly, Benedict Arnold committed treason, and is condemned for it in history, when he attempted to hand over West Point, New York and its thousands of soldiers to the British in 1780, during the American Revolution.
Some observers think Aaron Burr may have committed treason after leaving the Vice Presidency in 1805, attempting to seize part of the Louisiana Territory or take away Spanish territories further west. He was arrested, brought to trial for treason, and Chief Justice John Marshall ruled he had not committed treason by the normal definition, and conspiracy without actions should not lead to conviction. Still, many people then and since, think Burr was guilty of treason.
President John Tyler gave up his citizenship, and supported the Confederate States of America, becoming part of the provisional Confederate Congress in 1861, before his death in 1862, therefore committing treason.
Jefferson Davis committed treason, as President of the Confederate States of America, as did Vice President Alexander Stephens and other public officals, and arguably, General Robert E. Lee, and other Confederate generals, as well.
And now, it is becoming more likely that the 45th President, Donald Trump, has committed treason by colluding with the Russians to fix the Presidential election of 2016. The President is indicting himself by his own Twitter comments, and contradictory statements being made on a regular basis, and he exudes guilt, and has for many months.
The Robert Mueller investigation is mounting evidence that is leading to that conclusion, and the Southern District of New York investigation, particularly in relation to Michael Cohen, is also moving in that direction.
A proposal that I would wish to make regarding this whole situation.
John Tyler, when he died, was not accorded the normal situation of a President who passes away—that is, flying the flag at half staff, and giving a President a state funeral.
The same, of course, was the case with Jefferson Davis.
So it seems appropriate to say that when Donald Trump passes away, no matter what happens in the interim regarding the present investigation of his behavior and actions, there should be no flying the flags at half staff, and no state funeral, as a traitor should not be accorded such an honor.
Of course, his death and burial would be reported, but it should not be given the dignity of what every other President, except John Tyler, was accorded!
