Any discharge of a firearm within 300ft of school property counts as a school shooting these days. Even if it's a neighbor shooting a rabid possum in his garbage at 3am. You can be sure that will make it into the "statistics". OMG will someone please think of the children!
I did a school shooting once. With a BB gun. In physics class. As part of a lab experiment. Now, everyone would flip their shit. The Poz runs deep.
