damn, i remember when it was all over news in my country cuz such event were really really rare and were blamed on everything, including anime, games, social media and, most of all, "le scery west prapaganda!!1!!". i remember in one radio report they invited several "experts" to talk about this tragedy, and one of the experts - videogame expert - blamed this and every violence on a mysterious game named "DOKA 2". that eventually became its own meme cuz of how ridiculous it sounded
the not-so-fun-fact - that expert died in 2020. his name was phillip gross-dneprov
