Detective Don Flack: The kids who found him claimed that their friend's football may have killed the man. [Stella and Mac both give him a look] I locked 'em up just for fun.

Detective Don Flack: Yeah, and nothing says "I love you back" like an order of protection.

Detective Lindsay Monroe: Danny, you've been staring at that same piece of glass for five minutes. [Smirks] Can I bag it for you or are you waiting for it to turn back into sand?

Detective Lindsay Monroe: I need you to take this, okay?
Detective Danny Messer: Why?
Detective Lindsay Monroe: I'm no good with mothers, all right? Fathers, I can give bad news to all day long. I can't face mothers. I need you to take it.
Detective Danny Messer: All right. Okay, I got it.

Detective Lindsay Monroe: [Lindsay is looking up] She was stabbed with an icicle?
Detective Danny Messer: That's cold.
Detective Mac Taylor: Not cold enough. Our evidence is about to turn into a big pool of water.
[the icicle in the victim is melting]

Detective Mac Taylor: Absynthe spoon, a branding, a brutal beat down.
Dr. Sid Hammerback: I'll take Cult Rituals for two-hundred.
Detective Mac Taylor: I don't think so. Kid doesn't look the part. We have reason to believe he went to Chelsea University. [pause] What is a fraternity hazing gone bad?

Detective Mac Taylor: Don.
Detective Don Flack: Hey.
Detective Mac Taylor: You know why I'm here.
Detective Don Flack: Do you care about the consequences?
Detective Mac Taylor: I know this isn't easy for you.
Detective Don Flack: I'm not talking about me, Mac. I'm talking about the hundred of arrests this cop was involved in, the thugs who are going to be screaming for an appeal because his credibility's in question, and the ones who are going to go free despite the fact they're guilty and he did everything by the book. I'm talking about child molesters, rapists, murderers.
Detective Mac Taylor: Kym Tanaka's shooter stepped over his body and collected shell casings. He stuck his fingers into the victim's shoulder wound to retrieve a bullet all to save his own ass. He was there to sell drugs, poison, that destroys families, creates addicts out of babies in the womb, and accounts for twenty-three percent of the murders in this city. Don't make me subpena your memo book, Don. [Flack throws him the memo book. Mac walks away, stops, and turns back to Flack] The consequences I care about are the cops who never cross the line who now have to face critisim on suspicion because one of their own forgot the oath we took. Whichever one of these guys is found guilty I hope he goes away for a very long time because he disrespected the badge that you and I wear.

Detective Mac Taylor: Get dressed. Plunge is over.

Detective Mac Taylor: He took a genetics course of yours last year.
Quinn Brookman: I've had a lot of students.
Detective Mac Taylor: But only one of them helped you steal a body.

Detective Mac Taylor: I was just wondering. When you were making all those arrests, locking up bad guys, were you imagining a day when you'd be so busy kissing the Chief of Detective's ass you wouldn't remember what it was like to be a cop?
Insp. Stanton Gerrard: You son of a bitch. I don't deserve that. You know I'm here because...
Detective Mac Taylor: You don't have to explain it Inspector, I get it. You're just a puppet. I'll take my case to the badge that pulls the strings.

Detective Mac Taylor: I'm just asking questions, Don.
Detective Don Flack: No, you're not just asking questions, Mac. Come on, I know you. You wouldn't be here talking to me if you hadn't already tracked the chain of custody, checked with property, and called the DEA agents. And let me tell you something, cocaine from that raid wouldn't last six months on the street. So what is this? My interrogation?
Detective Mac Taylor: You're overreacting.
Detective Don Flack: Well maybe I am, but let me save you a little bit of time - none of my guys took a thing.
Detective Mac Taylor: You can't be sure of that. You weren't there. You just said you didn't remember.
Detective Don Flack: It didn't happen, Mac.
Detective Mac Taylor: You're listed on the DD5 as the recorder on the scene. You had to take everything down in your memo book - every detective who was there, who searched the room, who found the drugs.
Detective Don Flack: You askin' me for it?
Detective Mac Taylor: You can check your notes or you can let me do it.
Detective Don Flack: Is this official business?
Detective Mac Taylor: It's a request, from a friend.
Detective Don Flack: Then I'm gonna have to think about it.
[He walks away] .

Detective Mac Taylor: No. I don't feel you. If I find out you're lying, you're gonna be feeling me.

Detective Mac Taylor: So Sam's plan was to propose to someone else on the bridge, then pick up Erica Lancaster to "talk".
Detective Stella Bonasera: Translation: end their relationship.

Detective Mac Taylor: They belong to the gang we took down this morning. They're here for their coke.
Detective Stella Bonasera: What are we gonna do?
Detective Mac Taylor: Stop 'em!

Detective Mac Taylor: You got anything on the railing?
Adam Ross: That's a joke, right?
Detective Mac Taylor: Call it wishful thinking.
Adam Ross: Huh, it's got more trace on it than a public restroom. Actually, I have no idea what I'm looking for here.
Detective Mac Taylor: Sometimes you don't know what you're looking for until you find it.
[a tech hands him a folder] Thank you. [He opens it] Our photographer's prints didn't
match the print we found on the vic. We got a hit on someone else. See if you can put her
on the railing.
Adam Ross: [Reads the folder] Mandi Foster? Oh, oh, I love Mandi Foster.
[Mac smiles and leaves]
