Comet Ping Pong incident
On December 4, Edgar sought entrance to Comet Ping Pong to investigate Pizzagate. He was arrested 45 minutes later, after reportedly discharging a firearm, after which action additional guns were recovered by the police.(archived version)
Besides his background, there were additional signs this was a false flag operation to possibly elevate the Pizzagate situation to a threat so that the agencies can take action against the public investigation. A CCTV/traffic camera with the view on Comet Ping Pong reportedly was removed a day before the incident  as well as a lock-down of a two block radius, and additional camera movement.
A witness who was inside Comet Ping Pong at the time, Sharif Silmi, posted to Twitter that Edgar was arrested trying to hide a shotgun somewhere in Comet . Sharif himself mentions that he saw and heard no shots fired . This is a brazen contradiction to much of the mainstream media's alleged facts.
Three days after the incident on December 7 The New York Times interviewed Mr. Welch and asked about his motives and history. Welch stated that “The intel on this wasn’t 100 percent", and according to The New York Times conceded "only that there were no children “inside that dwelling.”" No clear motive was ever given as to why it was done other than to find imprisoned children, and he doesn't give the "sources" which led him to fire a weapon inside the restaurant, harming nobody. It's also fairly unprecedented that a newspaper would be granted a video interview with such a high-profile shooter on such short notice, but there is a consistent connection between The New York Times and anti-Pizzagate propaganda.
According to a sourced article on Heavy.com Edgar is said to have fired a single shot after employees and diners had fled, not multiple as is claimed, and that he had shot it into the floor. This seems to contradict Sharif Silmi's testimony at the time. There is also repeated claims that he used an assault rifle, and still other testimony closer the time of the event say it was a shotgun. Heavy's article now claims he brought two weapons into Comet. Overall there seem to be quite a number of elements to this story on which the mainstream media can't seem to agree.
Official police report
According to the official police report Welch was in possession of a Colt AR-15, Colt .38 handgun, and an "unknown" make of shotgun. Welch fired three shots into the restaurant, upon which an employee fled from the freezer to the exit. Welch pointed his weapon at the employee, but the nothing was harmed aside from a door, a lock, and the computer tower which can be seen mentioned above.
The original police report: 
Plea deal negotiations
On February 10, 2016 Edgar Welch pled not guilty to all of his charges.
Relationship to #Pizzagate
Connection to Judge Anita Josey-Herring and James Achilles Alefantis
Josey-Herring was the presiding judge in the case of the Comet Ping Pong shooter, US vs. Edgar Welch. The case was transferred to Judge Sherry M. Trafford for reasons that are not immediately clear.
On odds alone, that would be at least 1 in 55 of having Josey-Herring designated as a judge, as there are currently 55 other associate-level judges in the DC Superior Court (give or take some additional judges who probably left or joined the pool between 2011 and the end of 2016, as well some fewer judges as some appear specialized in certain areas like tax law).
