Good question. In Chicago, they are lying looooooooooooooow.

Very hard to say what the main rackets are these days.

They are really only caught for one-off penny ante bu$$sh$t, so there is no real clear picture about what, if anything, is going on large scale.

Possibilities range from basically defunct to the possibility that they have just gotten a whooooole lot smarter.

I think the overwhelming majority of evidence points to the former.

See the trial of Mike Sarno.
