Students strongly criticized the vote . The bill's sponsor, Carlos Guillermo Smith, noted the peculiarity of the timing of the rejection both because of the tragedy at Stoneman Douglas High School and because the Florida House of Representatives had just recently passed a bill declaring that pornography is a public health risk . </P> <P> In mid-March, Lori Alhadeff announced her own nonprofit organization Make Schools Safe, which will be mostly focusing on school campus security . </P> <P> In March, the Florida Legislature passed a bill titled the Marjory Stoneman Douglas High School Public Safety Act . It raises the minimum age for buying rifles to 21, establishes waiting periods and background checks, provides a program for the arming of some school employees and hiring of school police, bans bump stocks, and bars some potentially violent or mentally unhealthy people arrested under certain laws from possessing guns . In all, it allocated around $400 million . Rick Scott signed the bill into law on March 9 . The same day, the NRA challenged the law by filing a lawsuit alleging that the ban on gun sales to people under 21 is unconstitutional because it violates the rights that the Second and Fourteenth Amendments conferred to 18 - to 21 - year - olds, who were classified as adults . </P>
