Police responding to school shootings can learn from the US Marine Corps

Since World War II, US Marines had been taught to shoot by lining up on a range and firing at human sized targets with iron sights (traditional rifle sight before optics/scopes became standard).

This is the same way that most police departments train officers to shoot. The officers line up at a shooting range, stand still, look down the sights on their handguns, and fire at stationary human-shaped targets in front of them.

The most basic concept of marksmanship is lining the sight up with your target and firing before the gun or the target moves. But everything changes when the shooter and/or the target(s) start moving. The real world for Marines is shooting rifles with optics at all different distances while moving between streets, alleys, and inside of buildings. Shooting accurately becomes exponentially more difficult with obstructions, distractions, and multiple moving elements between a moving shooter and a moving target.
