There is no state preemption of firearm laws, with the result that some localities have outlawed the possession of handguns. This includes the Chicago suburbs of Winnetka,[2] Wilmette,[3] Morton Grove,[4] Evanston,[5] and Oak Park.[6] Highland Park also prohibits handguns, unless the resident has obtained a permit from the police.[7] Some municipalities, most notably Chicago, require that all firearms be registered with the local police department. Chicago does not allow the registration of handguns, which has the effect of outlawing their possession, unless they were grandfathered in by being registered before 1982.[8] Additionally, Cook County has banned assault weapons and magazines with the capacity to accept more than ten rounds of ammunition.[9] Other municipalities have also enacted various firearm restrictions.[10] Lack of preemption makes it difficult to travel throughout Illinois with a firearm while being sure that no laws are being broken
