According to AP, there were messages engraved on the casings in the Kirk shooting. They read:

• One read, “hey fascist! catch!” with an up arrow symbol, right arrow symbol, and three down arrow symbols. 
• Another one read: “oh bella ciao bella ciao bella ciao ciao ciao,” Cox said. 
• The third fired casing read: “if you read this you are gay lmao.”

My first thought is. Whoever killed Kirk was clearly inspired by Luigi. The writing on the casings just like Luigi did. The timing. It just makes sense.

Does this mean Luigi’s propaganda of the deed was successful? I think so. In any case, I wonder if this means there is more to come.
