Speaking of acting alone, one other famous shooter who “acted alone” was Lee Harvey Oswald. He too had a triple-barreled name like Thomas Matthew Crooks. Also John Wilkes Booth (Lincoln), James Earl Ray (Martin Luther King Jr.), Mark David Chapman (Lennon) and so on.

It’s like you can’t be an assassin if you only are called Joe Schmoe.

Also, it seems you can get assassinated only if you talk about peace and good things.
