BBC was interviewing an eye witness that was pointing out this guy to secret service and police for a couple minutes but they didn't do anything about it but only 'blew his head up' after he took the shots. The eye witness was saying there weren't many building in the area and there should have been enough security around those buildings.
SS and police were in in out it would seem.
Yeah this is the video I was talking about. SS and police stood down and only blew the shooters head up after he took the shots.
Remember that secret service stood down before JFK was assassinated.
