That page lists attacks in general, and not just at schools but also universities. Out of the 25 attacks listed for Germany (so since 1990), only 11 are shootings, and 14 have no deaths at all. So, you're right, Germany does know what school schootings are.

But compare this to a total of 67 (damn that number!) in the same timeframe in the UK ( https://en.wikipedia.org/wiki/List_of_school_attacks_in_the_United_Kingdom ), despite the UK containg about 20 million less people than Germany. Unfortunately, Wikipedia doesn't have a comparable list for France.

But both of those numbers just cannot compare with the US, where just the school shootings that Wikipedia lists (not all attacks, just shootings) add up to 882 over the same time frame. And its not due to higer population, the US only has about 4 times as many people as Germany.

Sorry, I realise you're kinda just trying to say, school attacks do happen in Germay too, and you're right. But you sent me down a rabbit hole. And the number of school shootings in Germany is so low that as a parent you can reasonably assume it won't happen (and they are rarely big enough to land in the news), whereas in the US it seems to be something that everyone thinks about, that schols plan for, and that has a not inconsiderable chance of happening.
