Exactly. Why can't we just pull their meta-data profiles from online, and just assess potential threat levels and weight it against the national threat level.

Threat level orange? Internet Anarchists and Armchair Libertarians don't fly.

Threat level blue? Just people who look like they have some desert heritage.

Threat level red? "I'm sorry sir. It says here you we're really, really mad at how a cop stopped you last weekend for going through a red light."
