The TSA now employs thousands of U.S. Marshals to protect flights, up from just 33 when 9/11 occurred. Our federal buildings have armed officers. Our most vulnerable should have the same protection.
Several studies confirm that most shooters who kill four or more victims are typically not psychotic or hallucinatory and haven't been treated for mental health problems.

In half of school shootings, "the shooter had no relationship to the school, was a parent, teacher, or staff, or his or her relationship to the school was unknown, according to the data.” Therefore, in about half of all cases, schools could not have met the social emotional needs of the school shooters because they were not students.
