I agree shootings do large societal harm past the students at the school (though to be fair, I'd say the opposite side could correctly argue that TikTok makes lasting changes to children/society beyond just the ones that use it (and may be correlated with depression/suicide, which is also profoundly sad))

Surely you have to do some kind of math eventually, or else you'll end up prioritizing whatever sounds the most dramatic instead of the things that actually matter (consider people who are more afraid of sharks than drowning, even though shark deaths are 1 in 4,332,817 and drowning deaths are 1 in 1,134)

I acknowledge that the numbers I'm using are not, by any means, conclusive. And I'm not saying we should prioritize TikTok above shootings just because it's more common. But this seems like a reason to get better evidence about the way the world is, not refuse to touch numbers because some harms are too sacred to attempt to quantify.
