"National Guard Lt. Anthony Circosta poses in his backyard in Agawam, Mass., on June 9, 2007. At left, his wife Danielle and daughter Kylie, 2, talk near the swing set. Circosta, a decorated Iraq War veteran, seemed like an ideal candidate for a pardon from then-Massachusetts Gov. Mitt Romney for the 29-year-old's boyhood conviction for a BB gun shooting. Romney denied the pardon, twice, despite the recommendation of the Governor's Council."
Maybe he denied the pardon because he likes to feel power over people.
