The JROTC students had more courage.
They did. Leftie report John Harwood says this incident proves that a good guy with a gun can't stop a bad guy with a gun - pointing to the trained and armed police officer.
But the police officer was a union government employee... and the ROTC kids inside were just brave people fighting for their lives.
Had the ROTC students (and coaches) been armed, instead of the police, this incident could have ended sooner with less loss of life.
