The Wire is one of those television shows that's like a secret society. To the outside world, The Wire seems like any other show about a police unit assigned to investigate crime. The title implies that at one point, an undercover detective is going to infiltrate an underground crime syndicate and eventually have his shirt ripped off to expose a small microphone duct taped to his chest, while a henchman observantly exclaims to the crime boss; "HE'S WEARING A WIRE"!
To those of us in the know, The Wire is a subtle masterpiece of story telling, that pulls no punches and allows you to witness both sides of the struggle. On one side, you have a rag tag unit of cops; each with their own vices. On the opposite side, you have an organized crime family that runs like a well oiled machine.
Oh, and let's not forget about Omar.
