Seems pretty clear that he was a far right, murdering scumbag who hated Jews, Foreigners and invaders [as Trump now likes to call them] and in killing innocent worshippers he was protecting the US of A.
The murderer in his own words...
// Gab, a social media site similar to Facebook and Twitter that is popular with white supremacists and other far-right figures, confirmed that it had deactivated an account in Bowers’s name following the shooting.
The account, which appeared to have been started in January, included a bio that reads: “jews are the children of satan.” His background photo was a radar gun that reads “1488,” a number that combines two codes — the “14” referring to a 14-word white supremacist slogan and the “88” being a neo-Nazi symbol meaning “Heil Hitler.” //
// “HIAS [Hebrew Immigrant Aid Society] likes to bring invaders in that kill our people. I can’t sit by and watch my people get slaughtered. Screw your optics, I’m going in,” Bowers is suspected of writing hours before authorities said he opened fire at Tree of Life. //
“I’m going in” was chillingly prophetic.
