Democratic Assembly member Das Williams is hopeful a bill he co-authored will prevent another mass murder like the tragedy that unfolded in Isla Vista last month.

Williams said AB1014 works like a gun violence restraining order. It would allow parents, spouses and others to ask a court judge to prevent a loved one from purchasing a gun if they are deemed a threat to themselves or others.

Critics call the proposal unconstitutional, but Williams said there is due process written into the bill.

State Senator Hannah-Beth Jackson is a principal co-author in the Senate.  Williams said the bill could pass the state Senate before the summer recess, but it would need a two-thirds majority vote with a special urgency clause to make it take effect right away.
