"Only 342 “assault weapons,” or semiautomatic rifles, were certified by Boulder police before the Dec. 31 deadline, meaning there could be thousands of residents in the scenic university town of 107,000 in violation of the sweeping gun-control ordinance. ..... Given that the average gun owner possesses multiple weapons, she said the 342 certificates could have been issued to as few as two dozen residents. She knows one owner who certified four firearms, another who certified eight." lol.
