Scott said he remained dissatisfied with the guardian provisions but signed the bill nonetheless, saying it would enhance school safety overall.
Three weeks after the Parkland high school shooting, Florida Gov. Rick Scott has a gun-control bill on his desk that challenges the National Rifle Association, but it falls short of what the Republican and survivors of the massacre demanded.
Under caveats to the "guardian" program, teachers who "exclusively perform classroom duties as classroom teachers" won't be allowed to carry guns on campus, unless they have military or law enforcement experience or if they teach a Junior Reserve Officers' Training Corps program.
IT IS now beyond doubt: The fearless student survivors of the Parkland, Fla., mass shooting are changing the debate about gun control.
The lawsuit names state Attorney General Pam Bondi and Rick Swearingen, commissioner of the Florida Department of Law Enforcement.
Scott received the $400 million bill Thursday following days of impassioned, often contentious debate in the majority-Republican House and Senate.
The legislation, while containing a number of other provisions student activists and their parents from Parkland had embraced, left out one of their chief demands - a ban on assault-style weapons like the one used in the February 14 rampage.
Tallahassee Mayor Andrew Gillum said that "Florida's elected officials simply have not done enough to stop our gun violence epidemic, and that remains true even with the Governor's signature today". "And that's healthy in our democracy", he said.
Gun control supporters said the tragedy - the deadliest US high school shooting ever - has given new momentum to firearms-safety measures pending in at least two dozen states, many in solidly conservative parts of the nation.
NRA sues Florida over new gun law, 'bill punishes law-abiding gun owners'
The complaint says the new law prohibits law-abiding citizens between the ages of 18 and 21 from lawfully purchasing a firearm of any kind.
The Parkland gunman "gave repeated warning signs that were ignored by federal and state officials".
Chris W. Cox, executive director of the NRA's Institute for Legislative Action, says the bill 'punishes law-abiding gun owners for the criminal acts of a deranged individual'. He noted that the same age applies to drinking. "The 21-year age limit just sounds reasonable to me".
Student activists from the school called it "a baby step".
Teachers, meanwhile, called on Scott to use his line-item veto power to zero out the $67 million set aside for the program to train and arm school employees.
"You said you were against teachers being armed".
"You helped change our state", he told the students attending the event.
The 19-year-old suspected of killing 17 people at the Florida high school excelled in an air-rifle marksmanship program supported by a grant from the National Rifle Association Foundation, part of a multimillion-dollar effort by the gun group to support youth shooting clubs.
Cruz's public defender has said he will plead guilty if prosecutors take the death penalty off the table and sentence him to life in prison instead.
