I don’t think we will ever get the real story on this as long as the fake news media controls information and the swamp in Washington remains. I think I can safely assume the nut was an anti-Trumper/Antifa but of course protecting Democraps must be the #1 priority.
If a person does not believe everything that the MSM says, and considers other scenarios, then that person is automatically considered a conspiracy nut. Which would make it easier for operatives to cover things up. ....I can remember back to the early stages of Benghazi news when I said it was a coverup for CIA weapons transfers and was called a conspiracy nut, rightly so, Im OK with being a conspiracy nut instead of a sucker ....but then again none of it matters because theres nothing we can do about any of it
