The mass shooting that got England on the list happened just down the road from me. Always weird to see it as part of some dudes statistical analysis.

I question the usefulness of using such small numbers in their analysis - if they'd have happened to pick the previous 15 years for the UK, will it so happened we had two mass shootings in that period so the rate would have doubled. Maybe in the next fifteen years it would have halved. What they should have done is compared the EU to the US, they are of comparable size and population.
