I’m not sure which part has been debunked. Do you have a link on that?

The news is now widely reporting the bullet casings were inscribed with some ridiculously long messages. (For a bullet casing, anyway. It seems like a lot of words to me.)

[Utah Governor, Brian] Cox said that there were inscriptions on the casings of the fired bullet and three unfired ones. The fired bullet casing contained the inscription, "Notices bulges OwO what's this?" An unfired bullet casing read, "Hey fascist, catch!" And a second unfired casing read, "oh bella ciao, bella cio, bella ciao, ciao, ciao." A third unfired casing said, "If you read this, you are gay."
