Sky Marshal Shooting in Miami

Bruce Schneier gives his views on the Sky Marshal Shooting in Miami. He thinks that it was not the same as the execution of Jean Charles de Menezes on the London Underground, and sympathises with the officers having to make split second decisions however:

"I'm not convinced the sky marshals' threat model matches reality. Mentally ill people are far more common than terrorists. People who claim to have a bomb and don't are far more common than people who actually do. The real question we should be asking here is: what should the appropriate response be to this low-probability threat?"
