MIAMI — Gun control legislation is moving at an unusually fast pace in the Florida Capitol following a deadly high school shooting, which has pushed state lawmakers and the governor to act after years of loosening restrictions on firearms.

Powerful budget committees in the State House and Senate signed off on a package of bills on Tuesday that would raise the minimum age to purchase a firearm to 21 from 18, mandate a three-day waiting period for most gun purchases, and increase funding for school safety measures and access to mental health care. The bills must still be approved by the full House and Senate, and approved by Gov. Rick Scott.

Included in the proposals is a contentious, $67 million voluntary program to arm school staff, including teachers, trained by law enforcement to carry concealed weapons on campus. Lawmakers gave preliminary approval to what has become known as the “marshal program” in spite of impassioned pleas by many parents of Marjory Stoneman Douglas High School students in Parkland, who said educators should not have to take on the role of the police. A similar program already exists in Polk County, in Central Florida.

Linda Beigel Schulman, the mother of Scott Beigel, a geography teacher who was killed, told lawmakers her son had become a teacher to teach, not “to be a law enforcement officer.”
