Maybe they should just start over?
It's impossible. "Dangerous person" is a speculation. The 9/11 hijackers had no record. Tim McVeigh had no record. People can't predict the future very well. For every bit of information that you choose to use to decide whether someone is dangerous, you'll have a large number of false positives and you'll miss "dangerous" people who don't throw off those indicators.
