Had an amazing debate about this tonight on a trading floor not far away, a few blocks. Envision a group of incisive people all sitting together unafraid to posit complex theories. Paring them down by belief system:
There is what I call the JFK group. This is the major league conspiracy theorists (“the CIA did it!”) - the ones who think this is political machination. Not my tribe.
There is the Jason Bourne group. They think this is all conspiracy, shooter was swapping out the Starbucks-purchased water for an identical bottle in his backpack that had the DNA of a dying patient on the mouth. The ones who believe events to date reveal significant training in evasion. Again, not my tribe, but I get how they got there.
There is the impassioned free-radical group. They theorize this is the kid or boyfriend of someone who died of a terrible disease surrounded by coverage denials, and they are avenging the pain, Joan of Arc style. That’s actually the theory I go with.
There’s also the disillusioned fired employee theory. I think we’d know the name by now if it were that. Discounting it for now.
Very open to hearing and learning from other theories!
