And that's the problem if you or the TSA can't prove that the BDO program is valid. Why then should we have to take the statements made by you or the TSA at face value. "Trust us it works" is not a valid answer.

This isn't about personal prejudices towards the TSA, this is about an agency that has reactive and ineffective solutions to real threats. Worse yet the TSA claims that everything they do is effective and then classify SOP's and other documents as SSI. Leaving the people who pay taxes and security fees no way to back stop these claims.
