A Senate proposal that would boost school safety and expand a controversial school “guardian” program moved forward despite continued backlash from teachers and students.

Alyson Sheehy, a graduate of Marjory Stoneman Douglas High School in Parkland, was among the many speakers who opposed the proposal. In tears, she revisited her firsthand experience from the mass shooting in February 2018 at her school and pleaded with lawmakers to not expand the “guardian” program to allow armed teachers.

She also referred to the suicides this month of a 2018 Marjory Stoneman Douglas graduate and a current student at the school.
