The U.S. Department of Justice issued model legislation Monday for so-called red flag laws that states can adopt, allowing courts to take firearms from someone who's deemed a threat.

Linda Beigel Schulman says the move would help save lives. Schulman lost her son Scott in the Parkland High School shooting in Florida.

"If a red flag law would have been in place before February 14, 2018, my son would be alive today and so would the other 16 victims of that mass shooting," says Schulman.

The Justice Department also released a proposed rule that would treat modified pistols with stabilizing braces the same as short-barreled rifles. That means they'd be subject to additional restrictions.

The revised guidelines, first promised in April by the Biden Administration, come after the country had another deadly weekend with gunfire breaking out in cities like Chicago, Cleveland and New York.

Some 2nd Amendment advocates say they're skeptical about whether these changes will make a difference.

"All these laws only pertain to law-abiding people. They don't pertain to the criminals because criminals don't pay attention to the law anyway," says Andy Chernoff, of Coliseum Gun Traders. "So although I would like to think this could make things safer and better for everybody, I also know criminals don't abide by the law."

Schulman says something is better than nothing.

The public has 90 days to submit comments about the proposed rule change.

Right now, more than a dozen states throughout the country, including New York, have red flag laws in place.
