Yep, I once was at an old steel mill in Pittsburgh where someone had stolen 10,000 lbs of copper cables by sawing them off with a sawz-all. The scrap metal place never once asked where he got it all.
I had to take an FBI agent and a Park Service officer to a remote compound shut down for the winter. Easier to access from Canada, scrappers came down on snow mobiles and cut every wire they could off an extensive solar off the grid installation. Quite a mess.
