Doesn't matter, the screener obviously didn't follow protocol. He let the individual go through 3 times when 2 is the max. And the way I read the post is that he let the guy through without any secondary which is a security breach right there. The screener had no way of knowing what was causing the alarm other than the individual's word that he had screws in his leg. I would expect better especially from BWI.
