Crackheads needing quick money. Probably already sold for $20.
About 10 years ago, our barn was broken into and lots of power tools were stolen, but the riding mowers and four wheeler was left alone. Jasshonkeys only got what they could carry and sell easily. Sheriff called Dad about a week later and said that they caught the guy, but he was part of a drug ring and had agreed to help gather evidence so basically they did nothing to him and our stuff was never recovered.
Bad thing is, if you're there to stop a break in or burglary and end up injuring the thief (or worse), then you could be held liable. Crazy!
