Is a correctional officer considered a peace officer?

Under Florida Law no. A licensed armed security officer is not a peace officer.

In the State of Florida you do not have to be sworn to have peace officer status. According to Florida Statutes 843.08 and 843.06 the Word "watchman" appears in both statutes. A security officer was once called a watchman. Therefore, a licensed security officer in Florida is a non sworn peace officer.
