Whether he can be convicted of treason or not, I am not going to guess. I can certainly see an argument that makes that case. Without actually being at the trial and hearing the presentation of evidence and the exact law, I cannot make a proper informed decision on it. I do believe he will end up with life in jail, so whether they actually call his crime treason or whatever does not significantly matter to me. He is not going to be executed, but he will never go free. I am pretty ok with that.
