1. A person who attempts to effect justice according to their own understanding of right and wrong, or an unauthorized person attempts to enforce the law. A citizen's arrest may only be effected when a civilian, out of fear for their own safety or the safety of their close friends or relatives, subdues or detains another who is violating the law.
2. A person who attempts a citizen's arrest or other vigilante justice in the vicinity of a peace officer or other authority who could otherwise carry out a legal arrest, whether or not a lawful Citizen’s Arrest.
3. A person who violates (12)10. Good Samaritan Clause.

NOTES
Vigilantism does not apply when a law enforcement officer in the vicinity is in need of immediate assistance, and a civilian aids such officer - for example, helping an officer apprehend an unarmed resisting suspect by holding him down.
