It may not help anyone but in case it does here's some notes I made a while ago - fwiw, I used the show as a learning aid to writing:
S1E1
Of all the 60 hours I think this first one needs to be properly understood else you’re behind the curve before you begin - everything from the kitchen sink to the Low Rise sofa is thrown at the screen. Here’s some of what we get; the hierarchy of the police department: Detectives > Sergeants > Lieutenants > Majors > Deputy Ops – that’s identified and explored though two separate departments Homicide and Narcotics. The personnel in both have been promoted from two Baltimore districts, the Eastern and the Western. The courts influence the police department but have no direct control. There’s the small matter of a ‘Detail’ being set up, whatever that is. You need a Ven diagram.
Beyond that core police hierarchy we learn a little about the State’s Attorney’s Office – we meet two women and a third is mentioned; we learn Assistant (State’s Attorney) Eileen Nathan is Violent Crimes, Rhonda Pearlman is Narcotics. We access the FBI at Special Agent level and learn it’s a separate and distinct entity and pulling out of the Drugs War to fight the War on Terrah. As an aside, we’re introduced to the technology gap – fibre optics surveillance vs. typewriters.
Alongside that we get a sketch of the Barksdale hierarchy; the other institution: Avon at the top, we know this because Stringer Bell withdraws when Avon wants to speak to D’Angelo. The goons are mentioned but remain in the background in the court scenes and outside the High Rise. Lower down, the wannabee youngsters are working the Low Rises.
In storytelling terms, McNulty and DeAngelo Barksdale tie everything together for us as they move around their organisations. They’re both in the dog house and the reaction of their co-workers and bosses is the mechanism by which we are introduced to, and begin to understand, those institutions – the writers nudge us twice: “chain of command”. They both reflect with a late night drink.
All in all we meet at least 20 central characters, maybe 25. There’s other stuff – the first glimpse of McNulty, Bunk and Kima’s after work life, the two addicts trying to shake down a deal, humour and stress in the car drug bust; it’s a frantic hour but the whole series/season is set up.
Fwiw, the flash back in the final scene of a dead William Gant (at HBO’s insistence) is the only concession in the 60 hours to helping the viewer - from here on we have to do all the work ourselves.
