You're missing the point: if the computer picks you out for some reason (perhaps you are ill, perhaps you are worried about losing your job or a family member's health, whatever), they won't care about the economic inefficiency or the infringement on your rights. Just because you don't intend to commit crimes doesn't mean you're immunized from bad decision-making by security systems.
Some of the responses to me were rude and I calibrated my responses to them appropriately. You stated I was "missing the point" which is more rude than me sincerely asking you to explain your rationale.
Your claims made very little sense. In my view, this potential new technology in no way increases the power of security personnel beyond what they already posses.
