  1. First, placing something into a garbage bin inside a private property does not make an object ownerless. Second, mistakenly misplacing an object whether it be a trash container or another location, does not take away any ownership either. Legaly, the finder was supposed to hand over the diamonds to the police. If the security guard would have done that, we would probably get a very nice finder reward from the grateful owner. Definitely, he would not be facing a lengthy felony sentence now.
