Vigilantes
The existence of costumed heroes raises interesting questions about the legality of being a superhero. Specifically, issues regarding the privacy of a secret identity vs. constitutional rights of suspected criminals to be able to address their accusers.
The identity of a registered hero is regulated by the Department of Extranormal Operations as part of their registry of metahumans. A registered identity comes with a state-issued ID that is accepted as proof of identity by state governments. This allows vigilantes to provide ID to law enforcement, make a witness statement, or obtain goods and services related to their work as a vigilante.
However, this means a vigilante is working as an actor on behalf of the state. Evidence gathered during the course of their activities is not considered admissible in court, even if turned over to lawful authorities, even under exigent circumstances. In some cases, use of metahuman talents to stop misdemeanour offenses can be problematic as well-- a citizen may only make a citizen's arrest if a felony has occurred and may not use lethal force to do so unless someone is in imminent danger of death or injury. Unlawful detention may result in criminal charges against the intervening individual.
Furthur, statutory law requires that an accused citizen be able to face their accuser in court. Vigilante identities are not acceptable when delivering testimony, either verbally or by affadavit. A vigilante who testifies in court must unmask and use their legal name to do so.
