I read through that whole list, and the only thing that involved any actual violence was a mafia killing, which it wasn't clear actually had anything to do with Q.

I don't know anything about this Q stuff (I don't even know what they believe), and I'm certainly not endorsing it, but your link does not support your claim.

The pizzagate shooting can be viewed as an early qanon consequence. Aspects of qanon are basically riffs on pizzagate, and the two factions have essentially merged.
