Probably the biggest news about the shooting now is the attempted blame shifting by just about everyone. But it seems none of it is sticking. The head of the Secret Service is being mocked because she claimed that the roof was "sloped" and thus dangerous for personnel. Total crap as the roof the sniper team was on was sloped and higher and possibly steeper than the one the shooter was on. There are also multiple videos of people standing on and walking on that roof. It has a minimal pitch.
The bottom line is that everything is the Secret Services responsibility. They are in charge, they delegate positions, jobs, etc. to all other law enforcement. Security is what they do. Local law enforcement certainly isn't very experienced at that and even the State Police have minimal experience providing security against serious threats. I'm sure they have teams set up for this but were they there? I suspect they were filled up by the local barracks. Pittsburg is close so they probably did have some experienced people there but the Butler County police? No. Local police are great at their jobs but that isn't providing security for someone under threat of assassination.
