Although possession of arms is at issue, the Second Amendment poses no serious barrier to enforcement of red flag laws. In District of Columbia v. Heller, the Supreme Court limited the individual right to keep and bear arms to “law-abiding and responsible citizens.” The petition itself does not render the subject an outlaw, or prove he is an irresponsible citizen. Rather, if the petitioner demonstrates that the stated risk is present, the law authorizes temporary removal.
