They certainly don't teach that stuff in school anymore. When I was growing up we used to take out our cap pistols at lunch and run around the playground shooting each other, playing good guys v. bad guys. Now if you even mention a gun in a public school you get expelled.
In light of these ongoing public shootings, we need to inform the public about tactics to keep casualty counts to a minimum. This guy not only stopped to reload probably a dozen times, but he also took the time to call 911 and give his verbal manifesto.
when I went to high school target rifles were a varsity sport...range in a school basement.
