The problem I have with it is, what will there criteria be for being a terrorist?
According to DHS, good reasons for killing you and blowing your dang house up can be:
Expressions of libertarian philosophies (statements, bumper stickers)
Second Amendment-oriented views (NRA or gun club membership, holding a CCW permit)
Survivalist literature (fictional books such as “Patriots” and “One Second After” are mentioned by name)
Self-sufficiency (stockpiling food, ammo, hand tools, medical supplies)
Fear of economic collapse (buying gold and barter items)
Religious views concerning the book of Revelation (apocalypse, anti-Christ)
Expressed fears of Big Brother or big government
Homeschooling
Declarations of Constitutional rights and civil liberties
Belief in a New World Order conspiracy
There's a long list of reasons to blow you and your home up here:
