You could be right on that one. Have you watched the second interview with the brother?
Interview with the evil killers brother. https://www.youtube.com/watch?v=SPZFN6VFFow
He basically explains that they were bad kids. His machine gun using bank robber dad, “was an asshole” left his Mom a single parent. His father later went on to kill himself. He says his brother was very intelligent and could do anything he wanted to. He does mention a couple of times that his brother would get angry and “bitch” about certain people or things. The reporters should have asked at that point, “what type of people/things annoyed him.” Given the fact that the brothers story has evolved from “we weren’t close” to “his brother made them wealthy and he was a great guy” I think he knows more about what kind of things made his brother angry.
Better hope their wealth isn’t tied together. Going to be a lot of civil suits brought against his estate.
Almost everyone I know well does this, sometimes. But I agree with you that the brother almost certainly knows more than he's letting on. I bet the Filipino girlfriend probably does, too.
My WAG: Paddock was probably an Obama/Hillary/Sanders far leftist who got pushed over the edge by Trump's election, and probably he started thinking about doing an attack like this several months ago, shortly after the election happened.
A country music festival screams out "predominantly white, middle American, southern conservatives". The perfect target for an enraged "Antifa" type leftist.
