Blue Bloods

Think every family in the Crime And Punishment genre is on the bad guys side? This family is different. The Reagan family is a cop family, not a robber family. A four-generational family with a retired Police Commissioner from Ye Goode Olde Days as the great-grandpa, current Police Commissioner Frank Reagan as The Patriarch, his sons who are all cops and his daughter who is a DA. And their children (two of which have declared they are seriously considering joining the NYPD). They live together, quarrel but stick by each other. Because the family that arrests together stays together.

They have different personalities. Grandpa Henry is a hardbitten Da Chief from the old days. Frank is an incorruptible patriarch and responsible leader, who knows how to keep peace between his children and how to encourage them without giving undue favoritism. Danny is a ruthless but competent cop who always catches the bad guys. Erin is a stickler for points of law but she can also manipulate the law to advantage when seeking a conviction. And Jamie is an idealist who feels a call to serve and protect. They are all loyal to each other and they all serve the cause of keeping order in the city of New York.

""I'm tired of playing second fiddle to the NYPD.""
 * Guile Hero: If Frank can't shoot them himself or put other cops in a position to shoot them, he's perfectly willing to outwit the bad guys instead. He even ran a Xanatos Gambit on a foreign ambassador whose son was a rapist in "Privilege".
 * Both Danny and Erin have a little bit of this in them too.

 * Loan Shark: Sgt. Renzulli gets in deep from betting on horses. Frank bails him out, with the explicit proviso that it's one-time only.

 * Mysterious Past : Both Danny and Grandpa Henry.
 * Myth Arc : Jamie and The Blue Templars. Started out as the main thrust of the series but was quickly shoved to the back burner, appearing mainly in Book Ends in the episodes where it's mentioned at all.
 * Nepotism : Zig Zagged . The Reagan clan is encouraged by family tradition. However there is no string pulling for them per se and they all become competent at their work.
 * New Meat: Jamie. He's slowly leveling his badass and becoming street smart under Renzulli's mentoring.
 * New York City Cops: The obvious focus of the series.

 * Our Mayors Are Different: Season two's Carter Poole is a Mayor Personable/Mayor Minority twofer.
 * Papa Wolf / Four Star Badass : In one episode Frank personally shoots a serial killer who is attempting to rape and kill Erin.
 * Henry certainly applies. When Frank was shot, the entire family was in the waiting room. After revealing that has a gun, Henry sits in front and the show proceeds to time skip a few hour. You don't think much of it, until you realize that Henry is the only one who's relatively alert. Meaning that he was guarding his family, as the only way to get to them was to go through him.
 * And then there was the time Henry pulled a gun on an EMT to save his son from meningitis.
 * It's also discussed earlier, as when Jamie is under an Internal Affairs investigation, Frank resists the temptation to tell IA to let him slide. Henry helps out by letting him know that the same thing happened to Frank when he was Commissioner, but he let IA go through because he knew Frank would be cleared. He was, and so was Jamie.
 * Passive Aggressive Kombat: Danny and Linda's marital strife spills over into a family dinner during grace. Danny compliments his wife's prayer, "especially that part about making good decisions."

 * The Patriarch: Frank.
 * Plucky Comic Relief: Renzulli.
 * Police Brutality: Danny has a somewhat shocking tendency toward this and sometimes the audience can't tell how far he will go. Given that it's usually towards quite despicable criminals, it comes off as Pay Evil Unto Evil.
 * In "Whistle Blower", an incriminating video of a cop assaulting an old man goes viral.

"Danny: We're in a union.

 * Protect This House: A father shoots dead the burglar who attacked his family, which is good enough for Danny. Not so much for the law, however, because a) the suspect was shot outside of the home, and b) the shooter is an illegal immigrant.

 * A Pupil of Mine Until He Turned to Evil: Billy Flood, one of the finest officers in Frank's unit.

""How does it feel to be defending a rapist?""
 * In the Papa Wolf example above, Frank proved pretty conclusively he doesn't need a Glock. His .38 Special works just fine.
 * Dedication reveals that despite his earlier advice to Frank, Henry carries a .357 Magnum revolver.

 * Salt and Pepper: Frank Reagan and Mayor Poole.
 * Sassy Black Woman: Danny locks horns with a power-mad nurse in "Leap of Faith."
 * The Scapegoat: After Danny's wife Linda chews him out over not mowing the lawn, the world becomes this trope. Culminates in a still-agitated Danny gunning down a fellow cop. ("Friendly Fire")
 * Screw the Rules I Have Connections: Inverted in "Parenthood," when the Mayor's daughter Ariel joins a protest and his caught up in the ensuring dragnet. Ariel doesn't demand special treatment, but her parents politely suggest, separately, that Frank had better let the matter drop.
 * Averted with Jamie, of course. With his family connections, he could have made Detective by now.

 * Tap On the Head: Oh, right -- Danny doesn't appreciate people pointing guns at Jackie, either.

Danny: Too late. [punches his lights out]"

"Jackie: What happened to you?
 * That Was the Last Entry: While listening to Joe's old iPod, Jamie uncovers a recording of his late brother preparing to infiltrate the Blue Templar.
 * Therapy Is for The Weak: Frank sourly tells his shrink that Reagan men don't go for prescription drugs. Or shrinks, for that matter.
 * Toyota Tripwire: A perp decides to rabbit and escapes on a scooter. He nearly mows down Danny, but doesn't quite clear Jackie's front bumper. Ouch.
 * Walker Family Dinner: What the family meals sometimes turn into.
 * The War On Straw: The show does not take a romanticized view of the NYPD Commissioner's office. Frank has butted heads with protesters and union reps. Zig-Zagged in "Leap of Faith", which seems to portray the archdiocese as a standard Corrupt Church shielding a anarchist priest. Though Frank initially opposes hs nomination for sainthood, after performing his own investigation, he decides things weren't so black and white in the Vietnam days. He even comes to the Priest's defense when the archbishops show signs of buyer's remorse.
 * The War On Terror: Mentioned from time to time. Frank was a 9/11 first responder and saw the towers go down; he suffers from Survivors Guilt as a result. He also has a peeve about people exploiting the tragedy to further their careers. Danny was a Marine who fought in Fallujah.

Anna: [icily] I grew up."

": [to Erin] I don't know what fancy place you come from, but from where I come from, there is nothing worse than a rat!"
 * What Do You Mean Its Not for Kids: An in-universe example. One weekend, while watching the twins, Henry and Frank have tickets to a Broadway play. It was about Christianity and bringing it to Africa, or so Henry heard. The name of the musical? The Book of Mormon.
 * Wise Beyond Their Years: Nicky pushes this trope hard.
 * You Are Not Alone: Frank reminds Danny of this at the end of "Silver Star", when Danny muses on how he could have ended up just like the victim, a homeless vet.
 * You Should Have Died Instead: The wife of a slain informant discovers that Erin was the one pulling his strings. "So because you suck at your job, I'm a widow and my kids don't have a father."
 * Your Cheating Heart: In "Whistler Blower", Erin's informant is murdered while spying on a white-collar criminal -- the same criminal who is . So much for wearing a wire.
