I guess this is where I'd love to have this discussion in person over a drink of your choice because my point, albeit unclear, was that these systems that, on the face of it, "solve crime" shouldn't exist no matter how much 'good' they offer. They have no control &/or limitation to their powers except by the person who decides to use them. I don't see that as manageable. Ultimate power breeds ultimate corruption, if you will. It seems we're at an 'agree to disagree' point & I'm OK w/ that result. Have a good day/week/month & please continue your efforts to healthy debate!
