I love this view (and coincidentally just started re-watching S2 last night).
Even in episode 1 of the season there are foreshadowing of these themes:
- Herc drops in to see Greggs and jokes about how bad the white gangs are at dealing drugs compared to the Barkesdales.
- The relationship between Sobotka and the port authority police is friendly and genial. They joke about what's going to be stolen. This is the opposite of the fractious 'us v them' relationships seen between the police and the gangs in the projects. Sobotka feels comfortable under the scrutiny of the law.
