The cops are wrong. I agree it's a sh1tty thing to do but show me the law.
Hey Mike - we haven't had a discussion lately. Hope things are going well.
Keep in mind this article is about a specific course in FL.
Looks like a commentor from that article found the law you were looking for.
http://www.flsenate.gov/Laws/Statutes/2011/705.102Quote705.102 Reporting lost or abandoned property.—(1) Whenever any person finds any lost or abandoned property, such person shall report the description and location of the property to a law enforcement officer.
(2) The law enforcement officer taking the report shall ascertain whether the person reporting the property wishes to make a claim to it if the rightful owner cannot be identified or located. If the person does wish to make such claim, he or she shall deposit with the law enforcement agency a reasonable sum sufficient to cover the agency’s cost for transportation, storage, and publication of notice. This sum shall be reimbursed to the finder by the rightful owner should he or she identify and reclaim the property.
(3) It is unlawful for any person who finds any lost or abandoned property to appropriate the same to his or her own use or to refuse to deliver the same when required.
(4) Any person who unlawfully appropriates such lost or abandoned property to his or her own use or refuses to deliver such property when required commits theft as defined in s. 812.014, punishable as provided in s. 775.082, s. 775.083, or s. 775.084.
Mike Hyzer was wrong. Stealing discs that people were too lazy or too unresourceful to recover is a sh1tty thing to do, and Rob M has shown me the law.
