The jist is that during training, the guy was scanned, and several of his coworkers noticed his penis showing up as fairly small.
So for a couple of weeks, they constantly made fun of him for it.
So one day, in the parking lot, he beat the crap out of one of the guys that made fun of him.
Every aspect of this is bad. The invasiveness of the technology, the screening of the mental states of the screeners, etc. It's unacceptable for the other screeners to take the power so lightly, and it's unacceptable for him to not be able to hold himself together.
I think everyone involved should be dismissed, and the higher ups who set the procedures should be reprimanded and given a deadline for resolution of their hiring practices.
I also think this should be a strong indicator that the technology needs to be modified to be less intrusive.
