They throw out easily debunkable information like this after events to muddy the waters.

They will put it out there so people who question the event will eat it up and disseminate it all over social media. Then when a sheeple comes along and sees it, they will easily find that it was debunked and will automatically disregard the rest of the legit information as bs.

Until you find solid proof, you would best be advised not use it as evidence. Not if your goal is to wake up people.
