what if? what if? what if? Jesus druff I am sure there is some scenario where the guy is a obvious criminal and you turn the wallet intact to the police.other wise you alert the person in charge where it was found and give it to them.

I have found a wallet on the street and went out of my way to find the owner with no expections just happy i found the owner. it is one of those pay it forward things.
for Druff selfishly it makes you feel good that you did the right thing and could brag about it over and over on a form that you owe and control.

its not your shit. "finders keepers" is for children and Gypsies.
