It would be ideal if they were absolutely terrible at identifying people but particularly good at detecting suicide vests. They do seem to be fairly narrowly tailored for the task at hand. TFA says they can discern large arms and bombs but not small arms. Assume the technology can progress even further to identifying small arms and weapons but that it’s passed through an audited AI running on trusted compute whose only output is calling the police when a threat is detected. Even then I’m willing to guess it would be a colossal waste of money that could save more lives if spent more effectively. Because terrorists just aren’t that common around here and if you’re detecting them carrying a bomb into the subway you failed a long, long time ago.
