You need to take a civics course.
Governors command the National guard and state police
Mayors command the police except for elected sheriffs
You're suggesting governor of the state has no business or is simply legally blocked or so afraid of the Mayor that the governor would never even consider simply calling the mayor and having a discussion? The governor is too afraid to ask the mayor why the cops would not be wearing cameras at this historic event that they wear daily while on duty anyway? Come on.
Ya ever notice these politicians seemed blocked, handcuffed and helpless to do anything. They all seem totally helpless, yet they all seem to have a built in excuse to just do as they please anyway when it benefits them. Very odd.
