The argument I'm responding to states that if you know someone is a terrorist, then you simply prevent them from boarding planes.
That anonymity is the source of crime isn't my argument, it's his.
Clearly, you can be identified as an 'enemy' and still be dangerous. A good example is during time of war, soldiers are often uniformed and standing in ranks. There is no doubt about which 'side' someone facing you is on, and yet they are no less dangerous because of it.
Anonymity doesn't remove danger, but merely identifies that danger exists.
Wouldn't it be interesting if you could flag something to notify you if you're walking by a white supremacist?
