The tradition of first day of school photos has reached law enforcement.

Facebook is flooded with photos of children holding up first day signs this time of year, so to see departments taking the same approach is pretty fun.

The Rochester Police Department, Olmsted County Sheriff's Department and Goodhue County Sheriff's Department posted photos of their officers and deputies on their first day of school in Rochester, Pine Island, Dover-Eyota, Byron and Kenyon-Wanamingo.
