The Loureiro case doesn't explain things much better than a conspiracy theory does. At least, after a few minutes of research, I'm still wondering if someone could have manipulated the suspect into finally acting on a decades-long beef that does not appear to have been escalating steadily. Perhaps the hard part is why he shot the other people, but an angry suicidal person could do that, whether they were acting alone or triggered by someone else.
