Ann Coulter, the acerbic conservative pundit, defended concealed-carry laws hours after a gunman killed 26 people in a Newtown, Conn., elementary school.
The laws, which allow gun owners in some states to carry covered firearms, have been a flashpoint for gun-rights activists who say concealed weapons help responsible citizens defend themselves.
"Only one policy has ever been shown to deter mass murder: concealed-carry laws," Coulter tweeted on Friday morning.
She linked to an op-ed she wrote in 2007 defending the laws after the deadly mass shooting at Virginia Tech, the country's worst school shooting.
The massacre in Connecticut -- one of the states that issues concealed-carry permits -- on Friday has the second highest death toll.
Adam Lanza, the 20-year-old who allegedly killed his kindergarten-teacher mother and at least 25 others at the school -- including 18 children-- was killed during the rampage. His cause of death is still unclear.
Gun rights activists, Coulter included, have been quick to deny the need for stricter firearms regulations, most recently after the mass shooting in a movie theater in Aurora, Colo.
