The protests — which consisted of student activists lying on their backs in the aisles of two Publix supermarkets — created a graphic image and brief delays.

The protest was held on the 19th anniversary of Columbine High School massacre in Colorado. The event is one of many that's been sparked by a mass shooting at Marjory Stoneman Douglas High School in Parkland, Fl. 

Anthony Borges was shot five times during the Feb. 14 shooting that left 17 of his peers dead.

Chanting “Vote them out!” and bearing signs reading “We Are the Change,” “No More Silence” and “Keep NRA Money Out of Politics,” hundreds of thousands of protesters packed Pennsylvania Avenue between the Capitol and the White House.

In addition to the backpacks, badges and metal detectors, Gov. Rick Scott recently ordered eight highway patrol troopers to begin assisting sheriff's deputies in patrolling the high school indefinitely.

A Florida judge ordered the brother of suspected high school shooter Nikolas Cruz to be held on $500,000 bail for a trespassing charge .

Security video shows a Florida sheriff's deputy going toward the high school building while a gunman massacred 17 people, before backing away and staying outside.

In a newly released recording from the day of a deadly Florida school shooting, the parents of a 17-year-old girl tell a 911 dispatcher their daughter is texting from a classroom where the door’s glass was shot out.

Florida's Republican-controlled Senate voted on Monday to generally exclude classroom teachers from a plan to allow school staff to carry firearms as part of a package of measures in response to a school shooting that took 17 lives last month.

The announcement Wednesday comes two weeks after the school massacre in Parkland, Florida.
