I wonder if the guy who runs the P.R. firm has monetary stakes in any of these conspiracy sites, (owner, partner, investor, advertiser, whatever) could be as simple as that, maybe he uses his legitimate business to gather info for a conspiracy side gig.
on the other hand disinformation can serve many purposes,.... is it a cover up because they don't want us, (the U.S. people) knowing what actually happened, and they're hoping it will get so muddied up it will just be forgotten about, or is it because they don't themselves know all the details and this is a tactic to cause the other players (the "bad guys") to mess up, get careless and eventually caught.... kinda like (as an example) if someone robs a bank the FBI reports over the news 150000 dollars stolen when in actuality it was only 100000 dollars, but this causes confusion and distrust in the criminals thinking each other is holding back which later leads to them messing up and getting caught.....a little different but just an example of how disinformation can be used.
what's kind of scary is that this type of sleight of hand would mean there are more players involved and still out there.
