Dealing in stolen property under Florida Statute § 812.019 means trafficking in, or endeavoring to traffic in, property one knows or should know was stolen. It is a second-degree felony (up to 30 years) — and becomes a first-degree felony when the offender has a prior conviction for this offense. When theft and dealing are charged together, Florida law bars both convictions for a single course of conduct, which is a key negotiation point. Defenses include lack of knowledge the property was stolen, innocent middleman conduct, and value disputes.
