Columbine High School was not in a "dodgy neighborhood". Nor was the shooting at that school in Florida a year or two ago. Nor was Virginia Tech in 2008.

In fact, I don't think any of the mass shootings in American schools have been in poor schools at all. Of course, they have their own problems with violence stemming from gang activity and poverty, but the mass shootings are in schools with pretty well-off students.

My question was posted in the context of its thread. Specifically, the figures we were discussing were about "gun related incidents", not mass shootings; the OP took the time to explain that these included things like brandishing a firearm or bullets striking school property whether or not there was a shooter on the property or someone got hurt. I would expect these sorts of incidents to happen more often in more violent communities; mass school shootings seem like they follow a different pattern than other kinds of gun violence.

While living i a "nicer" neighborhood does greatly reduce the chance of your child being the victim of violent crime in general, especially outside of school, the majority of deadly school shootings didn't happen in particularly "dodgy neighborhoods".

Do you have a citation? I could believe the most high-profile school shootings don't happen in dodgy neighborhoods, but the notion that school shootings generally are rarer in more violent neighborhoods seems counter-intuitive.

Let me revise my statement. I still suspect I'm right if we're talking deadly school shootings (most school shootings aren't deadly) but I'll have to run the numbers. A statement that is correct is that the majority of school shooting deaths the past 20 years happened in not dodgy neighborhoods.
