We had the LEOs run a sting about 2-3 years back when copper was going for $3.78/lbs..
They took a roll of copper to the three main scrappers in the area and each one bit. One even told the UC officer that he'd have to scrape the labels and tags off the reel before they'd buy it from him.
He complied and the deal was made.
All three got nailed.
Since then, things have tightened up and rightly so.
I've dropped scrap off at two of the yards and they run you through the ringer, now, before they even let you unload a pop-top.
Bad press will straighten out the worse operators REALY FAST once the ink hits the paper.
Maybe a few stings around the country might make a few others fly right.
Won't know unless someone gets off their butts and goes for the gold. (Pun intended.)
