But ID is not a requirement for travel: if you say you lost or forgot your ID, they’ll let you on the plane, subject to extra searches. Chris Soghoian writes:
The change of rules seems to be a pretty obvious case of security theater. Real terrorists do not refuse to show ID. They claim to have lost their ID, or they use a fake.
To me this doesn’t seem like security theatre at all. It’s simply that officials don’t like those who refuse to respect their authority. They respond by behaving like bullies. It’s no different to me being told off for holding a camcorder at a security checkpoint, or some bloke being told to change his T-shirt.
