How can you misuse data on school shootings?

Let's go a different way. Say you arrive home and you hear that there was a shooting at a school. What can possibly lead you to argue "oh that doesn't count, because X" ?

Why do you believe this is any relevant? I mean, to start off can you point out which incident fits your hypothetical scenario?
