About 2 years ago there was a wikipedia page listing all mass murders committed by one individual.
All but one of the worst 10 murders were committed without the use of a firearm. Including one case where a man killed about 100 people with a single gallon of gasoline.
I started pointing out this fact on various forums and very soon the page was replaced with one ONLY listing mass shootings. The non-firearm murders were completely delisted.
USSA here we are...
***about 100 people with a single gallon of gasoline.***
