His manifesto is very strange. And he is WAY too calm in the video itself. He definitely had training of some sort. He even went back in a second time to make sure he got any stragglers, double tapped, kept calm when he dropped his mag or the gun had a jam... Either way. Muslims are just the symptoms, the cause is welfare programs that enable the muzzies to have so many kids and want to come to the west in the first place. And the culprits are the politicians that let it happen, and ultimately, the lazy bastards that voted for more free shit.
