Nah, Srebenica was a bunch of shooters, right? An impressive number, still, sure.
The Tasmania shooter guy from Australia was a real character. For years his weird hobby if ever he was driving anyone anywhere was to lift his hands off the wheel, cover his eyes, and begin screaming —even if on mountain roads, etc.
This would force his passenger at the time to grab the wheel.
I think he also collected stuffed toys, too —there was a bunch of crazy stuff about that guy.
His target also was some kind of island resort that he set fire to, then started shooting up.
The Korean policeman guy had several days to go about his work, therefore his (until now) record of 60 rampage killings. He used some grenades, too, however.
Beslan, 2004, 354 dead.
The only “thousands” killed at Srebrenica were the over 3,000 Serbian Christians killed by the Muslims under Nasir Oric in the months preceding the final battle. In fact, the Muslim leader Oric used to enjoy showing visiting journalists videos of his troops massacring the Christians in the surrounding villages. After the battle, the Muslims retreated to the north toward Tuzla and were NOT massacred.
Port Arthur, in Tasmania, would be in there somewhere, too, iirc.
