In most states, pawn shops are the party that assume the most liability - if they purchase stolen property, and resell it, and then it's discovered that the property was stolen and has to be returned to it's rightful owners, the pawn shops have to make good on that - refund of purchase price to the customer, etc. They're the ones left holding the bag.
Exactly...Around here there is a Police task force that goes around to different pawn shops and checks out some of their items from time to time. Mainly those that carry serial numbers. I've have a few friends that have had their stolen speakers returned to them b/c the serial numbers on the speakers were still intact, they also had written down the numbers and kept proof of ownership. I know all my Milwaukee tools have serial numbers on them. I understand that after years of use those numbers get worn off, but it doesn't hurt to keep a record of them. I know it's a pain, but some tools have information cards that you can fill out to register that tool. On some of my high price items, I save the sales receipts, take a quick digital picture and write down, if any, serial numbers.
Also, a little bit of time with a number punch set might be worth it, too. Punch in a number in a hidden place. Say like on a drill, some you can remove a piece to replace the brushes. Put it in there, take a picture and document it. You never know what might help get your tool back. Or at the very least, have proof for your insurance.
