There was a serial killer named Joel Rifkin who preyed for years on SW's in NYC in the late '80's/early '90's...total murder count exceeded 50 before they finally caught him.  I would expect LE, now as is then, to concentrate their resources not on catching this evil scum, but on raising revenue from stings, and cow-towing to the human trafficking crowd that is connected politically.  In the meantime, who knows how many more ladies will meet a gruesome death because the authorities don't know or care to allocate their resources in the way that society demands?

Ladies, keep on screening as diligently as you can!   Quality hobbyists understand.  Never forget that LE is not your friend, and their main intent is to run you in.  Same for us hobbyists....
