Walking the line to come off as neither hysterical mother nor hypervigilant liberal -- women are already irrational, sometimes you have to show your work -- Alicia has to measure the situation that's happening as well as the possible legal battles that may arise from this, and being recorded. (Gosh, what does Alicia Florrick's pokerface look like? Uh, every episode of this show.) But it doesn't matter what she says, and she gets that vibe right away, because the cop is running through a script he made up for himself -- which inadvertently provides the first clue to its resolution:

Officer Robb: "...This roadway is a speed trap and easy pickins for drugs and drug money, so I just like to stop people and fuck with them in the hopes of getting my governmental masters a hefty payday which results in kickbacks for myself. So anyway, your son seemed a bit worried when I was talking to him just now..."
Alicia: "Uh, yeah. 17-year-old boys are scared of cops. Because everybody is scared of cops. Particularly when they've been pulled over for no reason at all."
Officer Robb: "You're probably right, but just to ignore the fact that your mouth is open and words are coming out of it, I'd like to just run my K-9 around the car so I can manufacture a false positive for drug paraphernalia."

Grace: "It's like a police state!"
Everybody: "Shut up, Grace."
Zach: "Just drop Dad's name."
Alicia: "Now, why on earth would I do that? I mean, I want you to explicitly explain your reasoning for that, because this is a teachable moment."
Zach: "Uh, this douche broke the rules first? He's using the law against us, for no reason I can see, so I think we can agree that use of the Florrick name is no longer beneath us."
Alicia: "First of all, this isn't Cook County, it's Madison County. And secondly, we don't use Dad's name. We use the Law."

(Chills.)

Alicia: "Hey, Cary? I just painted myself into a corner about throwing my husband's name around, so can you do some of my dirty work for me? Can you get this jerk's onboard camera?"
Kids: "Yeah! Let's fuck him up! Get him fired!"
Alicia, absolutely loving it: "Now, now."
