Michael Moore is calling for a new constitutional amendment on gun control as lawmakers struggle with how to respond to Sunday night’s mass shooting in Las Vegas, which left 59 dead and more than 520 injured.

In a post on his Facebook page, the documentary filmmaker and liberal activist proposed repealing the Second Amendment, which he called “ancient and outdated.”

A “28th Amendment,” Moore wrote, would demand that “the primary right of all people to be free from gun violence … shall not be infringed.”

Moore recommended that men must get spousal approval for firearm purchases, a requirement he says has “greatly reduced” domestic violence in Canada.

“As over 90% of gun violence is committed by men, in order for a man to purchase a gun, he must first get a waiver from his current wife, plus his most recent ex-wife, or any woman with whom he is currently in a relationship (if he’s gay, he must get the waiver from his male spouse/partner),” Moore wrote.

Moore’s proposal would maintain states’ rights to have an armed National Guard and would allow guns to be used for sport and hunting while instituting new protections for the public.

“The public’s safety comes ahead of an individual’s right to own and fire a gun,” he wrote.

Moore listed eight proposed restrictions on gun ownership, including banning all automatic and semi-automatic guns, mandating licenses for gun ownership, limiting guns and clips to hold no more than six bullets and requiring triggers to recognize the fingerprint of the gun owner.

“This is the sane approach that meets everyone’s needs — everyone, that is, except those of the serial killer, the mass murderer, the violent ex-husband, the disgruntled employee or the disturbed and bullied teenager,” he wrote. “We will never eliminate all murder; that’s been with us since Cain killed Abel. But we CAN join the community of enlightened nations where gun violence is that rare occurrence — as opposed to the daily tragedy we now suffer here in the United States of America.”

Democratic lawmakers are facing pressure from the left to introduce new anti-gun violence measures after Sunday’s shooting, which was the most deadly in modern U.S. history. 

Republicans have rejected the idea that such violence has a legislative solution.
