In the aftermath of this week’s high school shooting in Florida, Sen. Pat Toomey (R-PA) is calling for improved federal background checks for firearms sales.

In a Facebook post Thursday, Toomey said he and his staff will “continue to reach out to senators on both sides of the aisle to see where progress can be made” on the issue.

At Friday’s symposium “Responsible Reporting of Gun Violence” at the University of Pittsburgh, researchers discussed how to prevent mass shootings.

Russell Palarea, an operational psychologist who works in Bethesda, Maryland, works to thwart intentional and targeted acts of violence. He said that it’s a myth that people snap and then commit mass violence.
