After Sleeper surprises Conovan and his wife by hiding in the back seat of the car, there is a fairly tight shot of Sleeper looking down at his fingers and rubbing one fingernail with another as he speaks to them. Then the shot pulls back to show Conovan and his wife more completely in the front seat, and suddenly Sleeper's fingers are folded together as his arms rest on top of the front seat.

(at around 37m) When Piper is pinning mug shots onto the bulletin board, the arrangement of the existing photos changes between cuts.

After the fight in the hotel room with Lafe, Mike handcuffs himself to Lafe rather than cuffing Lafe's two wrists together. There is a high risk of personal injury and lack of prisoner control if a policeman is cuffed to a prisoner. Handcuffs are more effective if the prisoner's two wrists are constrained either in front or behind the back. Mike is injured because he is cuffed to Lafe when they are ambushed.

When Detective Piper introduces the young man that sold the .38 S&W revolver to the cop killer to detective Conovan the man says he sold the gun to a man in a bar. Conovan then grills the man about his getting a lousy eighty bucks for the gun that killed his former partner. But at no time did the man mention getting eighty bucks for the gun.

When Mike meets and dates Lili he is clearly wearing his wedding ring throughout. In the restaurant Lili finally asks him if he's married and then grasps his hand to show she doesn't care. The whole relationship with Lili to get information, with Lili in the know the whole time, as well dealing with his wife's reaction to the incidents is not quite believable for the character.
