The Washtenaw County Metro SWAT team and the county sheriff's office conducted a regular training exercise at the Washtenaw County Trial Court Wednesday morning, catching eyes with the mine-resistant vehicle parked on Fourth Avenue.

The regular training took place so officers can know the building “in the possibility we would ever require their services in a life-threatening or life-safety event,” according to a statement on the court’s website. The court was open during the training and visitors were notified of the exercise.

Armed officers in army-green camouflage uniforms entered the building holding rifles, being greeted by bemused attorneys and visitors to the courthouse. The county's SWAT mobile command center and mine resistant vehicle were both parked on the west side of Fourth Avenue, where uniformed officers stood by.

Ann Arbor police and University of Michigan police were aware of the training, as were Washtenaw County dispatchers.
