A few years ago, perhaps I wouldn't have considered it as an option. And I'm not advocating placing security cameras inside of restrooms. I think we have way too much CCTV coverage as it is already. However, if I were to justify it for any one reason, I'd say child abduction/rape would be a pretty good one. Unfortunately, it wouldn't prevent such acts. However, it would give law enforcement some investigative leads if there were videotapes of when the child victim was last seen and WHO ELSE was seen with that child.

Otherwise, I agree with your sentiment that it's a sad world IF we have come down to this. (Again, I'm not sure that any airports have CCTV coverage INSIDE of restrooms.)
