I was wondering the same.
Too many — media, politicians, FReepers — are quick to jump on the nearest bandwagon.
I never heard where the guy lived, but I wondered whether this was a crime of opportunity, rather than a crime aimed at this specific group.
Initially, there were reports of up to 4 shooters. That gave rise to all kinds of conspiracy reports.
I also wondered whether the guy’s girlfriend (they apparently had broken up recently) might have had any connection to this religious community.
Without something more from the shooter [a manifesto, a love-sick letter/message/Facebook, insights from family and associates] all this is just speculation.
What makes a person go crazy and start killing? That is an age old question.
Pretty much every single mass shooting I’m aware of had bogus multiple shooter reports.
These events are confusing and eyewitness reports are horrifically unreliable.
Usually something involving love and/or sex.
