He showed up to a protest with a weapon introducing himself to be part of a town militia protecting the town. He has altercations with
some of the protesters - they chase him, he kills two of them while wounding another. Sounds to me like he created
the circumstances of his own liking. Show up with a gun antagonize some protesters and then use it.
Not to forget, he went to another town, not one he lives in, with a weapon. Why bring a weapon? Most likely to use it.
Let's talk about the police in the town who did nothing but encourage these militia people carrying weapons. They appear
to be culpable in these deaths - they gave heart and encouragement to these militia types and one of them took them up on it.
Two died because they allowed weapons to be carried into a volatile situation.
