Los Angeles city council members are debating controversial new gun law changes aimed at locking up handguns when they're not in use.

According to the Los Angeles Times, the proposal would require city residents to either lock up handguns not being used or apply trigger locks to them. The proposal was authored by Councilman Paul Krekorian and is meant to protect children from gun accidents.

But the plan has faced resistance from the local police officers union – the Los Angeles Police Protective League. The proposed rules exempted active duty and reserve officers, but the union wants retired officers and their families also included, Fox News reports. They reportedly wrote a letter to lawmakers arguing that all officers need quick access for self-protection. The letter cited ex-LAPD officer Christopher Dorner's massacre of other officers three years ago.
