Thinking of this angle where the packages had mailing labels including return addresses for the Debbie Wasserman Schulz offices in Florida ...
Any chance that this Sayoc character had a job in the mailroom there, got fired or laid off, and walked out with some labels? Or at least made some up knowing what they looked like?
Would be interesting to find out if the return address labels are authentic (like what you might see on actual mail from there) or just a shot in the dark to create an authentic look.
On the larger question, actual pro-Trump nutcase, or elaborate setup, the smell test says wait and see. The detail of covering up windows with carefully prepared printouts (not posters apparently) seems inconsistent with the general profile we are given of this individual.
I think a line of inquiry (for the alternate media) should be, any chance this guy was targetted by operatives for some time in the lead up, and the van was redecorated in the time between first arrest and announced capture?
But even if he is exactly what they say, so what? In a nation of 350 million people with so many stimulants to insanity, any bizarre manifestation is not that surprising, last year it was the Las Vegas shooting (which still could turn out to have an entirely different explanation).
