1. Anyone have a good photo of the Helicopter that attacked DC protesters? I need a look at the tail. I note that they are not showing it on @washingtonpost. Also, what was the exact address? Finally, who runs the Hagerstown PA medical center?
2. Tail was rotary so I think it was this bird. Track of N304ME that was squawking around the time of the DC attack. Took off from Hagerstown PA Medical Center, flew to take a station over Anacostia River near Navy Yard. It then appears to have turned off its ADS-B transponder. 
3. Here is the place it took off. That yellow line is the track to DC in the above shot. It would have just required some paint and they could have changed the bird into a video prop.
4. Here is the bird's registration.
5. Here is the White house Communications Agency that IMO could have permitted the bird to fly in the exclusion zone. The operators would want to do a visible before they permitted the violation of airspace. Find the duty officer if he/she is not already dead. @FBIWFO
Correction: Hagerstown MD not PA.
