Meanwhile, I think someone who was one of Salem's agents at the time is the one who truly kicked off the war. Qrow said no one knows who shot first, who turned the riot into a battle. That stands out to me as leaving the possibility that who shot first was actually an agent of Salem, who purposely left it uncertain which side started it so that Mistral and Vale would blame each other. That's just her style, according to Qrow.

Admittedly, that idea clicked in my head thanks to FMA (the manga and Brotherhood, not the first anime), what with how the Ishvalan Civil War began.
