OK, so he planned a Vegas suicide and wanted to go out in a blaze of glory. He had probably been losing his grip on reality. I'm just not seeing politics or religion behind this. Not yet, anyways.
I'm sure it would be easier if he was wearing his "I'm With Her" T-shirt and has a Facebook page full of TrumpRage but as of yet, this doesn't seem to be the case.
I’m not saying it was religion or politics, I’m just saying the narrative isn’t fitting the evidence.
