Wolf’s office said Tuesday that the guard was mobilizing, or getting ready, to head to Philly. Guard members will help protect local property and supplement the Philadelphia Police, a Guard spokesman told NBC10.

Officials previously said that if the Guard were deployed, their primary role would be to station outside businesses. The National Guard was deployed this spring in business districts and other locations including the Municipal Services Building.

The day after the shooting and first protests Tuesday, Police Commissioner Danielle Outlaw said the department was “caught off guard” by unrest. But once the department realized there would be civil unrest “we immediately began to put resources in place” including opening an emergency command center, canceling days off and requesting aid from other law enforcement.

The unrest came as the city was making contingency plans in case of election-related unrest, Outlaw said Tuesday.

“We’re also planning for any pre, during and post unrest that may occur as it relates to the elections. So a lot of key people were already available and at the table.”
