Season 5, Episode 4, "Transitions"

WARNING: SPOILERS AHEAD! Kenard really ticks off Officer Colicchio by setting up a brown paper bag dog feces decoy, which causes him to assault a teacher and therefore forces Carver to grow as a person and as a cop. Proposition Joe tries to send out signals to Omar that he's upset about Butchie's death, but he doesn't take into consideration that Marlo, Cheese, and the Greeks are already making moves against him. McNulty and Freamon do their best to sensationalize the idea of homeless killings to get more mileage out of their police misconduct. Meanwhile, Daniels tries to do damage control with Burrell and Carcetti continues to eat bowls of shit when he realizes he has to appease every minister in town.
