It seems quite plausible that when they found the backpack it also had the gun and "manifesto" (stupid to call it that but it pushes their agenda) and whatever else in it, but they kept quiet about it. They only revealed that they had found the backpack. That would allow them to arrest anyone and then claim that he had the gun, etc. on him when they found him. They'll need to prove that those things weren't in the backpack they found.

I really doubt it. Cops barely have to prove shit when they're arresting someone for weed. In something this high profile and important for the establishment I doubt there will be much proof at all.
