What is your alternative theory?
What's this guys role? Is he innocent? Did they find an innocent man, plaster his truck with trump propaganda, because we all know those stickers are too clean! And who did it? Is it the deep state lizard conspiracy, or is it left wing radicals who are being covered up for by the FBI? Or was it the FBI? Give me anything that's even remotely plausible.
Oh sorry, I'm not a nutjob if I don't lap up what the papers tell me, only if I can't give a precise alternate theory?

I have no idea, did you expect me to?
