Being member of unlawful assembly

If a person knows facts that make a gathering an unlawful assembly, and still intentionally joins or remains in it, they become a member of that unlawful assembly. It applies where the person is aware of circumstances such as weapons, threats, or a common criminal purpose that make the group unlawful. Being a member attracts criminal liability under the Penal Code.
