I agree that should happen,but it won't. Kerry has been joined at the hip with the Kennedy Klan and the northeastern Dims ever since birth,and they are a clannish bunch that will gather their wagons in a circle around him and protect him.
Not only that,but even alleged Republican Senators that hate him will refuse to take part in the arrest of a fellow Senator. Hey! If Kerry can be arrested and put on trial for treason,so can they!
