Frank Reagan's Worst Moment In Blue Bloods Season 10

At this point, it seems fair to say that all of the main characters in "Blue Bloods" have made more than their fair share of mistakes over the years. The CBS series not only focuses on a family of law enforcement officials, all of whom are forced on a regular basis to make critical decisions while under intense amounts of pressure, but it also has aired over 250 episodes since first premiering back in September 2010. Taking both those facts into account, it's easy to see why none of the characters in "Blue Bloods" have necessarily perfect track records.

That's especially true for Frank Reagan (Tom Selleck), the wise but proud patriarch of the series' central family. As the NYPD Police Commissioner, Frank constantly has to ride the line between protecting his officers and holding them accountable for their mistakes. It's not an easy job, especially when several of his own family members are also active law enforcers. Like everyone else in "Blue Bloods," Frank has made plenty of mistakes throughout his time on the show. Sometimes, he's even failed to make them right.

With all that in mind, here's his worst moment in "Blue Bloods" Season 10.

In the second episode of "Blue Bloods" Season 10, Frank Reagan and his daughter, Erin (Bridget Moynahan), find themselves on opposite sides of a contentious issue. The episode, titled "Naughty or Nice," sees Frank and Erin come into conflict with each other after the former discovers that the D.A.'s office has compiled a list of NYPD officers whose past mistakes would make it difficult to take any of their cases to trial. Frank responds to the news negatively, considering the list a "blacklist" capable of ruining the careers of any officers whose names are included on it. 

While that's an understandable response for the NYPD Police Commissioner to have, it's hard to agree with how Frank handles the issue. Not only does he end up directing most of his anger and condescension towards his daughter, Erin, but he also uses her as his point of contact within the D.A.'s officer. In doing so, he effectively puts her in the middle of a conflict between her boss and her father. He also decides to call for a department-wide NYPD boycott of the D.A.'s office, ignoring the advice of members of his own staff and talking down to any of them who dare to raise their concerns about his decision.

Frank ultimately gets his way. He forces the D.A.'s office to abandon their list only by threatening to create his own, one that would name every city prosecutor that the NYPD believes may have fumbled any of their past cases. It's one of many moments in the episode where Frank lets his pride get the best of him, and it creates an uncomfortable tension between him and Erin that's difficult to look past.
