A rapist trespasses on one life, for his own edification, making him a criminal. A terrorists or alien belligerent/spy trespass on many lives, for a general ideal, making him an enemy.

How is it that you can't tell the difference?
How is it that you can't tell how the government will (not may, will) cheerfully abuse the power you seek to give it? How is it that you do not dread the prospect of President Hillary Clinton being able to indefinitely detain any American she deems a "terrorist" and an "enemy of the state?"
If Bubba Clinton had taken the tack you argue on April 19th, 1995, we'd both still be in "temporary detention for the duration of the emergency."
