However, Schneier misses one safety advantage to the current restrictions: LGAs appear virtually identical to explosives on our X-ray screens, so requiring screeners to at least stop and take a look every time they see a mass consistent with explosives, of a size that could take down a plane were it explosives, makes it much more likely they'd find the real bomb if one were present.
But each of these trips will have LGAs only the size of a tube of toothpaste, so it would not get the high level of scrutiny. The fact that they aren't really dangerous and that people are allowed to just keep trying until they succeed in getting whatever they want in the secure area, a little bit at a time, does make it a bit more of a farce than it already was.
