Makes me want a cave to hide in. But, on the Helps Police note... if only convicted criminals are scanned, at conviction not arrest, then this will only help them catch repeat offenders. New ones won't be traced, supposedly, unless they Opt Into the program. Of course, being the only one on the block who doesn't want to Opt In is likely to cause you problems... Then of course there's the flagging they mention. If you were stupid and stole something, say a belt, when you were 18... well when you're 40 and taking your kids school shopping you're going to be flagged as a thief... and when you're 60 and taking the grands... flagged as a thief. It would pretty much do away with the "Paid your debt to society" thing... your debt will NEVER be done. You will be watched for the rest of your life. Little creepy. Especially given how unpredictable our justice system is in the first place. Murderers walk free, and not scanned, so can't be placed at the scene. But the guy who got in a fight, served time, and is now out and being a good guy... he will get tagged as being in the area and thus becomes a 'person of interest'... Yes... yes I do realize I sound like a paranoid nut... but the flagging an old trespasser that bit was their words, not mine. If when they're touting virtues even they can't ignore that fact... or chalk it up as a good thing... who knows how far it could go. *sigh* Why can't humans just be decent... then there'd be no call for this kind of thing in the first place.
