A contentious theory I've often heard advanced is that if you told the police in any major metropolis "One hundred people. You know who they are. Go round them up," and they actually went out and got The Usual Suspects off the street at the same time, that crime in the burg in question would virtually dry up overnight, and stay dried up until those evolutionary niches could be re-filled by migration or reproduction.
You know the hundred people of whom I speak, too: Records that wear out the "pg dn" key on the courtroom computer while being scrolled through. On a first name basis with the local Five-Oh by the time you're sixteen. The cops not only know who you are, but have a rough idea of where to find you at any given time, like when they need to ask questions about the latest convenience store stickup.
Is this just one of the unsolvable perils of modern society? Any comments or thoughts by my readers in Law Enforcement?
EDIT: Since this has already been misconstrued as me saying "Screw the Constitution, let's go round us up some miscreants! Yee-haw!" 'cause that would be so in character for me... (this is me, rolling my eyes,) allow me to clarify that what I'm wondering about is the theory that in any given area, 90% of the bad stuff that happens can be traced back, either directly or indirectly, to a shockingly small number of people. I know from having lived in a small rural town that you'd hear deputies mumble that if the So-and-so family (and that one no-good layabout over on Rocky Creek) would just pack their whole clan up and move to the next county, then Smallville would become a dull place of a Friday night.
