Box cutters
A guy has been arrested after reporting lack of security that allowed him to carry 4 box cutters and 2 paint scrapers past airport security on 2 diierent flights. He was doing this to convinvce his wife that it is not safe to fly.
Newsflash: You can kill someone with a rolled up newspaper. They will never be able to screen out small objects that can be used as weapons. The government should be up front with this and get on with the sky marshals and locked cockpits. Do those two things and we will probably never see another hijack.
