Bingo!
He has a manifesto stashed somewhere easy to find, so you know exactly what he was thinking and why he did it. He planned the shooting out meticulously. But he forgot to plan his escape, and gets either dead or caught with lots of incriminating evidence. Calls for gun control flood the airwaves.
I wondered the same thing. All that planning, and he leaves a bottle with his dna on it and a burner phone behind (meticulous vs sloppy). AND he goes out for a hash brown sporting a set of the most distinctive EYEBROWS in the world knowing that law enforcement nationwide is looking for him.
To your point about guns in your community in upstate NY... I live in a high-crime area where it can take the police HOURS to respond (I kid you not), due to the overwhelming number of police calls daily.
When I lived in Europe, I was regularlly accosted by Europeans who admonished me for Americas "gun culture." They don't understand that here, you have to keep yourself alive until the police arrive.
But yeah, this whole thing screams of "look over there, not over here." Luckily not all of us are willing to drink the Kool-Aid when it comes to the Medical Industrial Complex (MIC).
