Fuller appears just then, holding a shopping bag aloft. Van Buren rolls her eyes all, "Get a hobby, old man, damn," and isn't appeased when it turns out that Fuller has brought them the pants. He proudly points to a spot of blood on one of the cuffs, saying it's probably Lily Yee's. He also admits that he found the pants in a closet in Cahill's apartment, which he searched sans warrant, on the grounds that technically it's Savings Mart corporate property. Green says that it's still Cahill's home and he therefore has the expectation of privacy, so Fuller disingenuously offers to take the pants back. After a beat, Van Buren says she thinks she sees some lipstick on the fly. Fuller: "You want them? Or not?" Lupo and Green answer by going in to arrest Cahill.
Bail hearing. Cahill pleads not guilty; bail is set at a million dollars, and Cahill's lawyer hands Connie a motion to suppress before they've even left the courtroom.
In McCoy's office, Connie and Cutter discuss the problem with the legality of the search for the pants -- Fuller isn't representing the government, but, McCoy says, he's acting on behalf of a giant corporation that behaves like the government. Which isn't really the point, because the standard is whether Fuller can reasonably claim that he was acting as a private citizen and not on behalf of the police, not whether his employers are Stalinist wingnuts, but if McCoy doesn't make that comment, we can't "enjoy" the ensuing thinly veiled and rather tired rant on the likes of Wal-Mart and how they'll stop at nothing to keep prices down. Done preaching to the choir, McCoy then tells us that, without the pants, the DA's office really has no case.
Cutter and Connie go over to the cop shop to make sure they didn't tell Fuller to get the pants, and didn't know that he planned to. They all deny knowing anything about it in advance; Lupo adds that they were just about to apply for a search warrant when Fuller shows up with pants in hand. Cutter mentions that Fuller is Van Buren's mentor, and she's like, true, but he taught her "to do police work, not outsource it to rent-a-cops." Zing?
At the suppression motion hearing, Fuller lies that he brought in the pants "at the request of Lieutenant Van Buren." Cutter and Connie exchange an oh-shit look, and Cutter gets up to remind Fuller that the three police officers swore they knew nothing about the pants ahead of time. Fuller's like, what do you expect them to say, and continues to assert that Van Buren "authorized" his search. The judge has heard enough; Cutter protests inevitable discovery, but it doesn't work. The pants are excluded. As you may have read in the men's room.
