The Buffalo Shooter is a lunatic and the desire to make political hay out the shooting is lunatic. His cut and paste manifesto, an F for plagiarism would be warranted, was merely a babbling effort to explain himself to a world as something other than he is: a madman. He fits a common pattern for mass shooters and we could do a much better job of detecting them before they commit mass murder if that was the goal. In his case he made no secret that murder was on his mind. Detection does not appear to be the goal however. The goal is rather for the Democrats in a bad election to use these murders to drum up their base:

If I’m not mistaken, cruelty to animals is something you commonly see in the lives of serial killers and mass killers. (Jeffrey Dahmer had a long history of it). My wager would be that his mother and father were confronting a series of odd phenomena to which they were flummoxed as to how to respond.
I doubt Payton Gendron qualifies as a madman under the M’Naghten rule (in contrast to Jared Loughner).
There are roughly 100 homicide cases in the United States cleared in a typical year which merit a firing squad, and the feckless characters who populate the judiciary and the state legislatures (along with the grandstanding shysters in prosecutor’s offices) have gummed up the works so badly that they cannot identify these cases with any degree of reliability and it takes nearly a decade from the time sentence is pronounced to carry it out. (And, of course, in many states it takes years to proceed to a verdict).

Bingo Art. I bet the record would reflect that they made attempts to get him help and everything they tried was unavailing.
Art, it’s called the homicidal triad: cruelty to animals, obsession with fire, and bedwetting beyond a typical age. Two or more in one’s youth is a huge red flag.
Neither “white replacement theory” nor “Tucker Carlson” appear in the manifesto. For that matter “fox news” also does not.
The manifesto does cite demographic results about whites becoming a minority in the US in the future. But Tucker Carlson was hardly the first person to talk about such results. In fact leftists talk about them all the time, praising the idea of whites not being a majority.
But this is a common leftist tactic: if you disagree with their conclusions they say something doesn’t exist, but if you agree with them they will say it exist and celebrate it. See for example Critical Race Theory, whether to teach kindergartners about homosexuality, etc.
“homicidal triad: cruelty to animals, obsession with fire, and bedwetting beyond a typical age..”
I knew a boy like this, we were both around 14 when he tortured and killed a cat, having set a shed on fire when he was 12.
They took him away and I never found out what happened to him nor do I wish to know.
