Those photos were taken in the gun-loving state of WI. The following states have assault weapons bans:
California, Connecticut, Hawaii, Maryland, Massachusetts, New Jersey and New York.
"Imports of assault weapons not already banned by administrative action under Presidents Reagan and George H.W. Bush were also halted. Assault weapons and ammunition clips holding more than 10 rounds produced prior to September 13, 1994, were "grandfathered" in under the law and can still be possessed and sold."
