This is an asinine argument, as a per-capita comparison with just about any other country shows. I'm not endorsing the Edweek numbers (which were brought into this discussion by someone asserting that school shootings are not a big deal).
I reject your argument that the media is to blame for hyping this. It is not normal to have people go into schools and start shooting children and teachers at random.
"It is not normal to have people go into schools and start shooting children and teachers at random."
We agree about that. If you mean "it's not okay" OR if you mean "it doesn't happen often".
Per capita comparisons aren't informative because you should care about the ABSOLUTE risk, rather than relative risk.
The ABSOLUTE risk (as I calculate in another comment, charitably about 0.000043% per year per student risk of being killed at school) is extremely small. The fact that it's 5x Greece's or something is irrelevant, because both are tiny. If you're trying to answer the question "How do I make sure my kid grows up happy and healthy?" worrying about school shootings is a waste of time. The kid has a 22x higher likelihood of being killed by drowning, focus on that. Or responsible drug use. Or physical fitness. Or driving safely (or not driving!).
Another basic thing you might want to keep in mind is: kids don't die much. Their overall risk of being killed from ANY cause is quite low. If you're worried about maximizing happiness or something, I wouldn't even worry too much about death. Sure, teach them to swim and when they're little make sure there's a lifeguard, but don't stress about them being killed unless you live in a war zone. (And I recognize that too many people live in war zones, and that's a real problem that real people have)
