From: Sean Caron <scaron at umich.edu> Nope. My wife used to work in commercial real estate. The building supers that she was managing money for *routinely* had multi-hundred-pound to multi-ton thefts of copper and other resalable material, often ripped out of walls over the course of hours or days. Size/weight are *not* a deterrent to a guy who is willing to steal an industrial air conditioning unit with a meth-head buddy, a couple of strap wenches and a beat up pickup truck cart it away in. Now imagine I tell that same meth-head that I'd pay him 5 times as much as scrap rates to steal something like what he's used to stealing, probably better packaged, but in a residence (no security guards). A touch of paranoia is apropos. KJ ?
