This should be a very easy test. In the years since these 3,000 behavioral observation officers have been hired, how many people have they identified as dangerous? If this number is greater than 0, the number of actual terrorists which existed to be stopped, then we know that it is an ineffective program. If they did identify 0 people, then we know it probably works! It's like school counselors looking for 'warning signs' of school shooters. If this is a reliable tactic, the counselors would identify 2 or 3 people every several years across the entire US. As it is, they identify dozens of students at every single school every single year - proving that they are monumentally incompetent.
