Another day in America and another senseless school shooting, this time in Benton, Kentucky. A 15-year-old student shot at least 14 fellow students, killing two of them, before surrendering to law enforcement. A witness said the shooter ran out of ammunition then attempted to run away but was apprehended without further incident.

Here is former Secret Service agent Greg Gitschier, a security expert, on situational awareness and how to self-protect during an active shooter event.

Gitschier details the strategy sequence of 1) run, 2) hide, or 3) fight. Listen to the audio linked above.

As for Kentucky’s gun tragedy, more details coming soon.
