"School Shooting" reports are often bogus:

Agenda, Not Accuracy | The Zelman Partisans:

Back in February, I fact-checked Everytown for Gun “Safety”‘s list of school shootings. 29% of their “school shootings” did not meet even their own definition.* Some weren’t shootings.

How would you define a "School Shooting"?

You would expect that someone at a school shot someone else at a school ... right?

Sorry ... most at least SOME of the stories about a "School Shooting" either didn't involve a "school", except only marginally.  Many don't involve a "School" at all, and some don't even occur within the boundaries of a school-ground.

I wouldn't have even mentioned that, except that the Popular Press is so eager to define gun violence as "School Shootings" that they neglect that often neither "Schools" nor "Shootings" were involved.

This is just one more example of how the "Popular Press" willingly glamorizes incidents in order to terrorize the public, in their urge to demonize firearms.
