As the state and nation continue to investigate the shootings in Twin Falls, Idaho, several talking points have emerged. It appears from many of the disturbing videos that the killer focused on those who were at the charging station. We have learned that an armed citizen and an off-duty law enforcement officer returned fire. Mr. Salinas began training in firearms after the Boise Townsquare Mall shooting. Greg Pruett of the Idaho Second Amendment Alliance told us this morning that the Twin Falls gun store was overwhelmed with firearms purchases following the shooting.
