A memo went out to the police department from Victor Joseph, commander of the Pittsburgh Bureau of police.

In the memo the department’s detectives are instructed to begin wearing a full uniform and carrying riot gear with them in anticipation of massive protests.

Police believe the protest would happen within 24 hours of Mueller’s firing.

“There is a belief that President Trump will soon move to fire Special Prosecutor Mueller. This would result in a large protest within 24 hours of the firing,” the emails states.
