Hard Cases - S2-E4
Corrected entry: Your hear one of the inmates saying the cut drugs were more rat poison than coke. Later in the meeting, where Avon Barksdale is going to tell them the source of the tainted drugs, his lawyer says it was heroin. (00:10:30 - 00:30:50)
Corrected entry: When McNulty emerges from the men's room looking plastered, the "men" sign is a mirror image, indicating a reversed shot. Also, one side of McNulty's collar is sticking out over his lapel. Sure enough, in the next shot, his collar is reversed.
Correction: The shot is not reversed, it is a reflection in a mirror. The mirror does not extend all the way to the bottom of the frame, and the bottles in the foreground can be seen with their reflections.
Misgivings - S4-E10
Corrected entry: Mayor-Elect Tommy Carcetti and Col. Cedric Daniels are at Carcetti's campaign office. On the wall is the political symbol of a donkey, which is for Democrats. Carcetti is a Republican, so the political symbol should have been an elephant. (00:43:57)
Correction: Where do you get the idea he was Republican? He was a Democrat and ran against Royce in the Democratic primary election. After that, he went on to win the general election against the Republican nominee.
Correction: The inmate says "more rat poison than it was dope" referring to heroin.
