You know when you cherry pick countries with 1 attack and a small population, then stack Norway with 1, finland with 2 etc and proclaim "look these small places should be compared per capita with the US, 1 attack surely is enough data points", then don't look at the combined EU and state that gun legislation is fine? Maybe you even misrepresent (frequency, literally noone claims that mass killings cannot physically happen elsewhere, what the actual f) what the person you are 'fact checking' said and change nothing when it's pointed out to you?

Yeah, that is what you just posted.

This is the typical handwaving from the right. None of these incidents are even remotely comparable to what has happened in the US over the last decade in totality. Andres Breivik swings these stats in a way that is useful for this agenda.
