first sentence of his manifesto tells you straight that he is a bootlicker:

To the Feds, I'll keep this short, because I do respect what you do for our country.

NB: I will not perform sleuthing, i.e. reading up on this guy or anything he wrote. I don't think it's worth it

I think it is odd that he in the several days between the murder and the arrest kept the gun and the fake id he used in New York. Doesn't prove anything, people have been known to do odd things, but then again police also have been known to plant evidence or make claims of evidence that doesn't stand up in court. Guess I will await the trial (if there is one).
