"Knee-jerk reactions" to school safety fears after a school shooting in Parkland, Fla., have created civil rights concerns for students of color and students with disabilities, a group of civil rights organizations said Monday.

After a school shooting at Marjory Stoneman Douglas High School, students will be processing their trauma for years to come, a teacher told lawmakers.

A focus on students' social, emotional, and academic development improves classroom learning, a new report says, but teachers need support to bring that mindset into their work.

Florida lawmakers passed a bill that includes restrictions on gun purchases, school safety measures, and a voluntary program to arm school staff. Gov. Rick Scott has not said if he will sign it.

Prevention is an important part of school safety plans, experts say. But the public isn't always aware of successful prevention efforts, and that can skew debates over school safety.

Robert Runcie, the superintendent of the Broward County district recovering from a Feb. 14 school shooting, called for an independent review of the "educational record and the academic, social and emotional services" that accused gunman Nikolas Cruz received while he was a student.

Obama-era guidance that calls on schools not to rely on police to administer routine student discipline "may have contributed to systemic failures" to report a school shooting suspect's behavior to law enforcement, Florida Sen. Marco Rubio, R-Fla., wrote in a letter to U.S. Secretary or Education Betsy DeVos and Attorney General Jeff Sessions Monday.

The Broward County sheriff's deputy assigned to Stoneman Douglas High School took position outside of a building during the mass shooting there last week, but he never entered to try to stop the gunman, Sheriff Scott Israel said Thursday.

Even before President Donald Trump proposed training and arming teachers in response to a mass shooting at a Parkland, Fla., high school, some teachers there said they wouldn't want to carry a weapon in their classrooms.

Deputies who patrol Broward County, Fla., schools will carry AR-15 rifles, the same weapon that was used to carry out a mass shooting at one of the district's high schools last week, Sheriff Scott Israel said.
