If someone is repeating watching beheading videos, engaging in terrorism forums, reading bomb-making instructions, and other such material, then I would rather prefer the police and the justice system to get involved. Better that than another terrorist attack that could have been stopped.

It saddens me that a rational move to prevent terrorism in its formative stages leads to such a knee-jerk negative reaction, with commenters ranting about "1984" and "infringing our civil liberties" and "leftist censorship" and other such overreacting nonsense.
