Yes, I remember at least a couple of those kinds of shootings as well.
But I'm talking about a kid just showing up and indiscriminately shooting people for no reason. Two guys having a beef with each other - yes, high school kids killing people just for fun - no.
The shooter in Massapequa in ‘58 was already a ‘troubled’ kid and being treated by a shrink. It was such an anomoly that we remember it 55 years later.
