I dont agree that just because the Constitution says the President can do something doesnt necessarily mean it couldnt be a crime. The President is the commander in chief but he cant order the military to do anything he wants. In this case though I agree with Dershowitz thats its not even close. Even Hillary agreed that Comey should be fired. He was plainly in dereliction of his duty.
You are so far from your tagline it's not even funny. The President can in fact order the military to do anything he wants.
There are military and political checks in place and those orders may not be followed but the President is commander in chief.
