Jennifer Walsh: Some people say that your rigid adherence to department policy is more pliable than you let on. That you've been known to look the other way and be creative with those policies on more than one occasion.
Mac: They're entitled to their opinion.
Jennifer Walsh: And so are you. I came to hear your side of the story.
Mac: There is no story. I do my job to the best of my ability and I expect the same from all the officers under my command.

Jenny Harper: Wait, you don't blame him, right? 'Cause he wanted to keep it?
Don Flack: I think he was very lucky that he had a girlfriend who pointed him in the right direction.
Jenny Harper: Yeah, that direction got him killed.
Don Flack: The men who stole those gems placed a tracking device on them. So they were probably tracking Heath's movements. The fact that he was bringing them to us didn't save his life, but it might've saved yours.

Jerald Brown: Willie and I just picked any pig cop. An eye for an eye.
Det. Mac Taylor: You shot a New York City police officer. He wasn't just a cop, he was somebody's son. He made somebody proud at home. When you shot him through the back, you shot those people through the heart. [Mac stands up] From where I stand... you're the one that should be put to death. No trial, no jury. Eye for an eye.
[about the shooting of a police officer in Central Park]

Jimmie Davis: Mac Taylor. Heard your voice on the phone, I couldn't believe it. Now you're standing here. Look like your old man. Been a long time, Mac.
Mac: Since we were kids.
Jimmie Davis: Yeah. Last I heard you were in New York, married, working for the mayor's office or something.
Mac: I'm a crime-scene investigator.
Jimmie Davis: Phew. Must be something, huh? What's the statute of limitations for us sneaking into Wrigley? What brings you back, Mac?
Mac: Bobby Toole is dead.
Jimmie Davis: That's supposed to be funny? He's been dead for 30 years.
Mac: Yeah. But they found his body today, in the Tribune Building.
Jimmie Davis: We swore we were never gonna talk about this. I haven't told a soul.
Mac: Somebody put his body in the Tribune Building for me to find, the word coward on the wall. Did you do it, Jimmie?
Jimmie Davis: What? What, are you out of your mind, Mac? Huh? Is this some kind of sick joke to you?
Mac: Over a month ago I got a T-shirt stained with blood. I didn't know until today, that's your brother's shirt. Will's blood. The same shirt he was wearing when Bobby Toole beat him to death.
Jimmie Davis: You feeling guilty, Mac?
Mac: I don't regret the choice I made that day.
Jimmie Davis: No, I don't imagine that you do, because you didn't lose a brother. Your family didn't fall apart. You didn't watch your father cry for the first time in your life, watch him crumble to his knees. You didn't spend ten years trying to make it up to your mother and your little brother, lying to little Andy about how Will died. Not you.

Jo Danville [about serial killers]: Neglect, it was the most common form of abuse in their childhood.
Lindsay Monroe: He murdered his brother, then he goes on a shooting rampage. Getting to that point cannot be that simple.
Jo Danville: No, it's not. It's usually a preexisting condition, a genetic anomaly of some sort that renders them susceptible.
Mac Taylor: Nature combined with nurture.

Jo Danville [to Adam]: I got a courtesy call from an old friend of mine at the FBI. Turns out the Feds have been investigating Dragga Financial for all sorts of shenanigans. In fact, they were kind enough to share their files with me, pretty much all of it. But they weren't too keen on seeing an NYPD computer digging around in their sandbox.
Adam Ross: Okay, that's great. But I know why you're here. I've heard about your rep. So what, are you gonna blow the whistle on me now, too?
Jo Danville: You don't want to go there. Me leaving the Bureau to come here was about conviction and evidence and doing my job.
Adam Ross: Okay. I'm sorry. That w... that wasn't fair.

Jo Danville [to Adam]: You're being ridiculous.
Adam Ross: What?
Jo Danville: You deal with death every day. This case is no different. Man up.
Adam Ross: Are you kidding me? Jo, I saw this girl alive. She's not just another dead body on the slab to me. Oh, no, did you just do that so I'd spill my guts? Oh, damn it!
Jo Danville: Sorry, Adam. You can't keep your feelings bottled up. Contents may explode under pressure.

Jo Danville [to Mac]: Don't you want to join us? This burger is just heaven on a sesame seed bun.
Mac Taylor: Well, maybe next time. I've already had, uh, heaven on a bun for lunch.

Jo Danville [to Torrey Powell]: You swallow a lot. I mean a lot a lot. I don't mean to make you feel self-conscious. It's a common OCD anxiety disorder. And I would recommend exercise or some kind of organized sports to keep your mind focused on something else. But since those really aren't an option now, you're kinda screwed. Unless...
Torrey Powell: Unless what?
Jo Danville: Well, the sympathetic nervous system is responsible for your body's reaction to stress and right now, there's no question you're under a great deal of that. So you're gonna need to really figure out how to alleviate that somehow.
Don Flack: How about by telling us the truth, Torrey?
Jo Danville: It's a matter of your personal safety.
Torrey Powell: What the hell kinda mind games are you playing, lady?

Jo Danville: (To Sid) Can you tell us anything about the nature of the blunt-force object?
Sid Hammerback: (Stares at her, doesn't say anything)
Sheldon Hawkes: Sid?
Sid Hammerback:: I'm sorry, I just wasn't prepared for you to be so...
Jo Danville: Female? (smiles)

Jo Danville: 50 kids jumping up and down. Whoever the morons were decided to add a table should have known that was a bad idea.

Jo Danville: (about finding the dead girl upon her arrival at the crime lab) My first thought was, "It's a practical joke. You know? Welcome to the New York Crime Lab."
Mac Taylor: We usually sabotage a pair of latex gloves or have a tech pose as a dead body in autopsy, then suddenly pop to life, but murder? Not our style.
Jo Danville: Good to know.

Jo Danville: (on the phone) Hey, what's up? No. No. Because I said so. No, no. Absolutely not. Because I (looking at Mac, a bit embarrassed) said so. I love you, too.
Mac: Was that your son?
Jo: No, my momma.

Jo Danville: [amused] Dr. Sheldon Hawkes, did I just hear you say ghosts?
Don Flack: You did. Wanna know why? 'Cause that's what he said: Ghosts.
Sheldon Hawkes: A lot of New Yorkers believe this part of the park is haunted. The lake just over there, for years rumor has it, two women have been seen skating figure eights, at night. Rosetta and Janice, sisters, died in the 1800s. Apparently they just glide above the ice, if you get too close they disappear.
Don Flack: [amusedly scared] Shut up.
Sheldon Hawkes: Yeah. Then there was that real estate guy that got gutted by the river just east of here. Oh, and Belvedere Castle, tons of people have heard disembodied voices, and dispatch gets calls all the time.
Don Flack: Teenagers. Doing the nasty.
Sheldon Hawkes: go ahead, poke fun, but this area where we are, right now, some of the volunteers from the emergency medical unit won't even ride in here, they send me. I gotta be honest, there have been times when I felt something.
Jo Danville: a prescence?
Sheldon Hawkes: I dont know.
Don Flack: Doc, come on. You can't tell me, that in your well educated mind, you don't have an explanation for paranormal activity.
Sheldon Hawkes: ok, one night, I heard a woman screaming. I get off my bike, I run towards the sound, the screaming is getting louder and louder, but when I get to where she should've been: nothing. Nobody.
Jo Danville: What do think it was?
Sheldon Hawkes:I don't know. I don't have a rational explanation for what happened that night. Now, it could have been my mind playing tricks on me, or maybe it was the sound bouncing of the trees; but I felt something weird here, and judging by the looks of these shoeprints, maybe our Jane Doe felt something too.

Jo Danville: [To Ellie] I adopted you because you needed me... and because I needed you
