Well the gun store originally said that they got a verification so they sold the kid a gun. Then the FBI said oh now we have a hold on him. Its like trying to document smoke.
All these shooters have funky haircuts, a thousand yard stare, are on psychotropic drugs and many of these incidents have multiple witnesses saying more than one shooter. Then later just one shooter.
I don’t know about this particular incident but based on recent history its not out of the realm of speculation to suspect false flag. Its pretty easy to take some nutty kid on drugs and put a gun in his hand and point him in the direction you want him to go.
So the government is always suspect given the atmosphere we are currently living in. Hey it got rid of the Confederate flag in a couple of weeks with almost no fanfare. A mighty achievement in the South.
I'm thinking Lee Harvey Oswald syndrome.
