A ruling by a superior court judge has struck down a new law designed to regulate the purchase of ammunition.
In the process, that ruling also calls into question the ban on armor-piercing bullets that has been in effect for more than a decade.
State Senator Kevin de Leon (D-Los Angeles) has introduced a bill with language designed to protect that ban.
L.A. County Sheriff Lee Baca and Los Angeles Police Chief Charlie Beck offered their support.
"We have to control ammunition," said Beck. "We're not standing here by chance. Behind us are 203 badges of Los Angeles police officers killed in the line of duty."
Beck said the judge's ruling also jeopardizes the ban on minors buying ammunition.
