Fighting crime family style. It's the formula that has kept "Blue Bloods" going strong on CBS for more than a decade. The crime drama follows the Reagan family, which includes current NYPD field intelligence sergeant Jamie Reagan (Will Estes), detective Danny Reagan (Donnie Wahlberg), district attorney Erin Reagan (Bridget Moynahan), current NYC police commissioner Frank Reagan (Tom Selleck), and former NYC police commissioner Henry Reagan (Len Cariou).
