Mark Wahlberg on 'Patriots Day,' blue lives, and his own past with the police

April 15 will mark the fourth anniversary of the Boston Marathon double bombings that killed four people and injured more than 260 near the finish line. The new film “Patriots Day” chronicles the race against time to hunt down the perpetrators, the Tsarnaev brothers, before they could strike again. Mark Wahlberg, an actor and co-producer of the film, as well as a native Bostonian, stopped by to speak with Yahoo News and Finance Anchor Bianna Golodryga about his character, the process of getting the story accurate, and his relationship with police officers now.
