This one will be a hot mess, indefinitely. Any investigating body from the federal government will be mistrusted. That many people involved will generate literally thousands of different and contradicting eyewitness testimonies. The 24 hour news cycle and rush to be first will generate misinformation and disinformation. Internet trolls will muddy the waters.
It will probably go on for years. People still believe the DC sniper had some connection to jihad.
Particularly since McCabe is leading the investigation. Can you say coverup? McCabe you may
recall lead the Hillary (non) investigation and the investigation that concluded there was no
political motivation involved with the DC softball shooting where the shooter asked if the ball
players were republicans.
Our government would never lie to us.
