It's just speculation. No real motive has been determined. https://www.latimes.com/world-nation/story/2025-09-12/what-we-know-about-the-suspected-killer-of-charlie-kirk

LA Times wrote this less than 15 minutes ago:

Investigators are still looking through evidence and trying to determine a motive in the slaying.

The only things in writing are the words etched into the bullets, and those are mixed. He wrote an anti-fascist statement on a bullet casing and other text on others, but nothing to indicate he had liberal or conservative ideologies. If anything, he appeared to be mostly mad at the whole system.

Some Twitter guy has multiple awards for journalism, I'm inclined to give him some benefit. But I would like someone to provide an official statement.

That's what I'm waiting to see. We have to be patient.

Not to mention the stuff on the casings was specifically antifascist.

Most articles actually said the complete opposite of what this shitter post claims.

Cox said: "The family member referenced a recent incident in which Robinson came to dinner prior to September 10, and in the conversation with another family member, Robinson mentioned Charlie Kirk was coming to UVU."

There was a mention of how "Kirk was full of hate and spreading hate".

Most articles also say that one of the bullet casings had a "bella ciao" engraving which could be false flag but also could be real.
