What is disconcerting about this is the definition or lack thereof of "hostilities". If you are a United States citizen you are entitled to the legal rights of a United States citizen. Regardless of your opinions or crimes. Do I believe in prosecuting domestic terrorists- absolutely. But without the legal rights of citizenship, any American accused could be easily stripped of their ability to acquire legal defense. I fear it could be abused to thwart freedom of speech as opposed to its intent to dissuade/punish treasonous activity.
