There are some things that does not add up. For what I read of the so called manifesto. He is poor. Where did he got the money to buy the rifles, ammo and magazines. The Red Dot sight, is pricey and is add on, also the furniture adds to the cost. I found odd to enforced the "Whitie" meme. On the video. On one point in the video it has a misfire. These rifles are not that easy to operate, you have to practice. He seems to have no issues there, so where did he practiced. Operation seems fairly good. Where did he got the time and money to practice. The Red Dot sight needs Zeroing. The camera. Perfectly placed in a "Video Game" fashion and decent video quality. I trully hate to see people loosing their life on this maner. Not sympathy for the perpetrator. But some bothers me on the execution of it. Like this guy had some sort of training.
