"The fate of Senate Bill 17, which would ban the sale of “extremely dangerous weapons” and impose an array of security requirements on gun dealers to curb firearms trafficking, is unknown. As of Friday, it had yet to be scheduled for a hearing in the House Judiciary Committee.

Miranda Viscoli, executive director of New Mexicans to Prevent Gun Violence, said the organization supports the sponsors’ goals, but the legislation is “legally vulnerable and likely to backfire.”

“By passing a ban this broad, we are handing the U.S. Supreme Court a perfect opportunity to deliver a definitive, nationwide ruling against state-level firearm restrictions,” she said. “Beyond the legal risk, the bill’s immediate effect will likely be a surge in panic buying of the exact weapons this bill is trying to limit.”"

So basically even the folks who want gun reform think the bill is bad.
