Our Constitution wasn't written so that the party in power at any particular time can cherry-pick the requirements needed to arrest an individual under military jurisdiction. A United States Citizen while in United States territory should NEVER be subject to military arrest and/or military trial at the whim of the government, regardless of what they have been accused of.
Well said. I have no great objection with detaining citizens engaged in terrorism abroad, who are on the battlefield, so to speak. Try them in a military tribunal.
But when it comes to detaining citizens without trial in the U.S., that is a step too far.
