Surely this can't be a new tactic? I would call for reexamination of the domesday book data ...
"Criminals" didn't get smart just in the last 5 years. People who won't do what they're told have been around forever, you shouldn't underestimate them. And I don't mean to portray them in a better light than they deserve, but assuming that their only intent is ever to undermine your personal world is as big a mistake as you can make in this life.
The world was not created with a bunch of anglo-saxon rulers at the pinnacle, that assumption is concreted into the law frameworks we use in most western countries. Since most of the world comes from outside that genre, most people don't see our systems as things they should automatically respect -- and haven't, habitually, forever.
So it should be no surprise when they 'think outside the box' and if you don't think outside that box often enough, you are at a disadvantage materially, and spiritually, and in a human sense.
Giving personal information to strangers is a risk, even if the strangers are government certified. I take that risk every ten years or so not under any illusion that 'my data is safe' but because I believe that this system of data collection is beneficial in maintaining systems that provide effectively for our welfare.
The incidence of white collar crime is known to be extremely high, and the natural point for criminals to attack is actually higher in the chain than at the collection point. These guys are the 'easy prey' for the law enforcement, as numerous stories indicate the more effective criminals do a very solid job of ensuring that they do not become exposed.
We should see reports like this one as indicitive of the rate of penetration higher in the system. It would be interesting to see statistical analyses which show the correlation, ie does 10% penetration and imposterisation at low levels indictate 5% at mid levels and 1% at higher levels? Or perhas it indicates 20% at mid and 10% at the top .. etc
Such figures would be particular to particular societies and societal segments, but I think they would generalyl be fairly stable, with observable indicators of societal disruption when they skew far beyond the established norms.
PhD thesis in criminology, anyone?
