Criteria for Determining Criminal Gang Membership

Broader rules for identifying gang members

Beginning October 1, 2026, Florida law changes how authorities identify criminal gang members. A person must meet at least two criteria, but one act can satisfy more than one. Criteria include admitting membership, including online, or being identified as a member by a gang, reliable informant, or cohabiting parent, guardian, or spouse. An informant whose reliability is untested needs support from independent information. Other criteria include gang dress, hand signs, tattoos, physical evidence of membership, or association with known gang members. The repeated-observation criterion drops from four occasions to two; observations in custody count only when association is willful. Criteria also include writing communications showing gang affiliation, gang activity, or accepting responsibility for a gang member's crime. Using gang-related language online to further criminal gang activity also counts. Gang-related language includes spoken or written statements signaling gang ties or activity, plus recognized gang codes, symbols, or terms. The updated definitions also apply to public nuisance rules. Gang membership becomes an aggravating factor in sentencing for a capital felony. County and municipal detention facilities must designate someone to assess inmates for gang membership or association using these rules. They must send that information to the arresting law enforcement agency at least every two weeks.
