While the political focus may be on mass shootings, states are far more often using red flag laws to prevent cases of individual gun violence, including suicide.
It may not be a coincidence that several mass shootings took place in one week. Research shows perpetrators are often inspired by media coverage of other shootings.
Federal judges said a lower court was wrong to dismiss the former vice presidential candidate's lawsuit against the newspaper over an editorial that linked her to a 2011 mass shooting.
President Trump wants to expand laws that allow courts to intervene when someone shows signs of pending violence, and lawmakers are getting behind the idea. But are these laws effective?
"I want to praise the defendant's grandmother, who saved lives by interrupting this plot," said a federal prosecutor. She was able to convince her grandson to go to a hospital.
U.S. attorney for the Western District of Texas, John Bash, said the investigation into the deadly attack is proceeding with a "view towards bringing federal hate crime charges."
"We must do more than give our thoughts and prayers; we must give Virginians the action they deserve," Northam said of the shooting at a municipal complex in which 12 victims and the suspect died.
Most of the victims were city employees, and many worked as engineers, account clerks or administrative assistants. The suspected gunman was also a longtime municipal employee.
