Albuquerque Police Department
Officer Baker & Officer Saxton
Two police officers assigned to investigate the burglary of Wormald's house.
Detectives Coleman and Salerno
Two detectives who interrogate Wormald after police officers discover the secret compartment in his house.
- Lying to the Perp: They try to convince Wormald they just want to help him get his baseball cards back. Fortunately for Wormald, Jimmy and Mike know what's really going on and are able to get Wormald out of trouble.
Detective Dunst & Detective Russo
Two detectives assigned to find the missing Kettlemans.
- Manipulative Bastard: After Jimmy lays a hand on Mike, the two detectives try to manipulate Mike into threatening to have Jimmy charged with assault unless Jimmy talks his client, Nacho, into confessing to the kidnapping.
A detective assigned to observe Mike's interrogation about the deaths of Hoffman and Fenske.
An undercover police officer who learns that Jimmy is selling drop phones and decides to intervene.
- Undercover Cop Reveal: He is in plainclothes and doesn't identify himself as a police officer. Jimmy figures it out, but Huell doesn't until it's too late.
Philadelphia Police Department
Officer Matt "Matty" Erhmantraut
Mike's son, and Stacey's husband. A police officer in Philadelphia who was murdered after his corrupt colleagues suspected he wouldn't have their backs.
- Calling the Old Man Out: Stacey remembered him having an argument with Mike prior to his death. Mike said it was when he tried convincing Matt to go along with the corruption as he did, which pissed Matt off to know his father was a crook.
- The Ghost: He never appeared on-screen.
- Posthumous Character: He's long-dead before Better Call Saul starts.
- Screw the Rules, I'm Doing What's Right!: Matt refused to be corrupted and had intended to turn in Hoffman and Fenske. His hesitation got him killed.
- So Proud of You: In two ways. He was very proud of his cop dad, to the point of becoming one. And, his dad was very, very proud of him; and, not just because he became a cop — he always considered his son a better person (not without cause). The problem was, the corrupt reality of the work environment twisted everything between them, although Mike will never stop being proud of the son he feels he failed.
- Too Good for This Sinful Earth: Only cop that wasn't corrupt and refused to walk along until his dad broke his heart with the Awful Truth, still got killed by his partners because they were scared of a change of heart.
- Uriah Gambit: Was set-up to be killed in an ambush
Officer Troy Hoffman & Sergeant Jack Fenske
Partner and commanding officer, respectively, of Mike's late son Matty.
- All for Nothing: They murder Matty Ehrmantraut because he showed too much hesitation in turning dirty, like them. They were afraid he'd go to Internal Affairs, but Mike had already convinced Matty to go along with it. They kill him anyway; even from their twisted point of view, Matty's murder was senseless.Fenske: You got something you want to get off your chest, something you want to say to us?Mike: You killed him. You killed Matty. And you killed him for nothing. You killed him because you were scared of what you thought he might do.
- Boom, Headshot!: Both are shot in the head by Mike.
- Dirty Cop/Killer Cop: They take kickbacks from gangs, steal from evidence, that sort of thing. But when they're cornered, they outright murder their own, killing Matty Ehrmantraut when they fear he'll rat on them.
- Posthumous Character: They're both dead before the start of the season.
- Those Two Bad Guys: They're thick as thieves, which makes sense, since they're thieves in addition to being killers.
- You Killed My Son: The pair of them murdered Mike's son. They are repaid in kind.
Detective Greg Sanders & Detective Abbasi
Two Philadelphia detectives brought out to Albuquerque to question Mike.
- Hero Antagonist: Abbasi is pretty nasty to Mike and determined to see him locked up, but only because he (rightly) suspects Mike is hiding something criminally big. Mike seems to understand that Abbasi is just being a good cop.Sanders: That whole precinct was a sewer. Wouldn't be surprised if there's a few more early retirements. Might be a good thing: new blood.Mike: Like the kid.Sanders: Yeah. He's all right.
- New Meat: Abbasi, as Sanders acknowledges.
- Old Friend: Sanders is a pal of Mike's from back in the day.
- Wide-Eyed Idealist: Due to being the New Meat, Abbasi doesn't quite get how things work just yet and thinks he's going to bring Mike in. He isn't.
