I didn’t dig too deep on the stats for school shootings (because oof), but thankfully we’re not there.
The post says "shot" not "killed". I've only done a superficial search, but looks like
Each day 12 children die from gun violence in America. Another 32 are shot and injured.
So the post is only off by what, a week or two?
E: assuming that the 12 killed are also counted in the 32 shot, otherwise the meme is underestimating it. (E2: which, reading again, is an assumption I shouldn't be making because it clearly says that another 32 are injured, so yeah, we're there)
^the meme beat you to it lol
Though good job trying to find those numbers (genuinely)
