Not only that, the conspirators must have been really dumb to send "bad actors" if they can so clearly be seen faking on YouTube, or what about the child they send to get photographed after her death? What, they didn't keep tabs on the actors? Which would be completely insane since the last thing a conspirator would want is his own team running around and blackmailing him. And who are all these actors? Do they sit at home all day until they are used? What a dream job - being a bad actor and getting paid by the millions to do bad acting!
Last, what has really changed? Did the government knock down the doors of every gun owner in America and confiscated all their guns? What can't gun owners do that they could do before the shooting?
I think you do understand that to believe this conspiracy theory you have to throw out every bit of logic. This conspiracy leaves too many witnesses, the government has no logical motive, and no one else could pull it off.
