Supervisor Pat Herrity (R-Springfield), center, stands with McGruff as the crime-fighting bloodhound gets ready to take a bite out of crime during National Night Out events across Fairfax County in August. McGruff, the popular canine, started the night off at the West Springfield District Station, where he was joined by fellow law enforcement officers and Supervisors John Cook (to McGruff’s right) and West Springfield Police Captain Joe Hill (next to Cook).
