I think the biggest benefit to NOOP was awareness. While many will still be anything for safety I think the videos and first hand stories from the screening abuses will be TSA down fall. The grandma getting felt up, grandpa getting his colostomy bag broken open, the new mom getting hassled because of breast milk, etc. etc. Those are the innocent americans being hassled (not saying that we all are not). With build up with that comes the question what did the patdown or Nudiscope accomplish.
BTW Some of are of the opinion that it is all theatre but use the AIT cause it is the least offensive.
