What Happens To Brandon Routh's Doug Stanton?

Doug Stanton first appears in Season 3, Episode 2, "In Justice." When Jackson West's training officer, Angela Lopez (Alyssa Diaz), is promoted to detective, Stanton steps in to lend his experience to train the young officer. West notices something off about the veteran officer and begins to suspect that he is a racist, witnessing him profile civilians and call them gangbangers and bros. West stands up to him when he reads a situation where Stanton looks to be about to use excessive force, only to garner his wrath.

While Stanton threatens to fail West out of the Field Training Program and end his career as a police officer, drawing a return threat from West to use his Internal Affairs father, the veteran uses a different approach to deal with West. When they respond to a call in an apartment complex known for its dangerous criminal element, they split up, and multiple people attack West. Instead of coming to his partner's aid, Stanton stands back and allows it to happen. When other officers respond, Stanton pretends to check on him.

At that moment, West reaches up from his ambulance gurney and turns on Stanton's body cam, knowing the device records the two minutes before activation. The resulting footage shows Stanton refusing to help him and gives the Mid-Wilshire team all they need to get rid of the officer, suspending him pending investigation.
