The supreme court in Heller held that the bearing of arms is an individual right. I think all you anti-gunners should be prosecuted under the appropriate statute.
Title 18, U.S.C., Section 241
Conspiracy Against Rights
This statute makes it unlawful for two or more persons to conspire to injure, oppress, threaten, or intimidate any person of any state, territory or district in the free exercise or enjoyment of any right or privilege secured to him/her by the Constitution or the laws of the United States, (or because of his/her having exercised the same).
It further makes it unlawful for two or more persons to go in disguise on the highway or on the premises of another with the intent to prevent or hinder his/her free exercise or enjoyment of any rights so secured.
Punishment varies from a fine or imprisonment of up to ten years, or both; and if death results, or if such acts include kidnapping or an attempt to kidnap, aggravated sexual abuse or an attempt to commit aggravated sexual abuse, or an attempt to kill, shall be fined under this title or imprisoned for any term of years, or for life, or may be sentenced to death.
