First off... you could of avoided spaming the website and instead just posted the numbers and where you got your data from.
Second off... where are you getting your data from?
Looks like Wikipedia lists... but a lot of those under the US aren't under the Wikipedia list.
Third off... it's good you chose the UK and not a number of other countries... otherwise... (also you know, the list is unfinished.)
Finally.. just looking at "Rampage killings" part here but...
since 1982...
it looks like 31 to 6. Which is 5.1 times.
Edit, lets just add in school shootings
UK 5ince 1982.
Looking at it though, looks like Mother Jones was wrong on the amount of shootings... practically everywhere. More common then I would of thought, but still not really enough for statistical significance.
