Those are different classes of &quot;mass killings&quot;, Wikipedians aren&#x27;t going to collect all the cases of where 4 or more people were killed, and my postings were not intended to discuss scale, just to refute the lie that this is a uniquely American phenomenon with 2000-~2012 examples.<p>Which is not quite what you claimed, you said &quot;overwhelmingly&quot;, and that&#x27;s sufficiently vague I suspect it&#x27;s a debatable point.  Paywall stops me from the WSJ article, but I know that people who study this sort of thing that I trust have said at minimum the FBI&#x27;s recent study was bunk, and that&#x27;s enough for me on this topic.
