The New York Police Department is secretly run by Shane McMahon
This theory comes from a couple of posts
on the tv.com message board for the episode "Avatar." The poster's theory about Shane O Mac belongs in Wild Mass Guessing
His special mount is his motorcycle. His "occasional moral lapses"
indicate that even though he's a Paladin, the cynicism of the Law & Order Universe
, he's fallen every now and then... but that's what the spell Atonement
This was implied by the writers — he seemed to have way too much money — but never explored.
He could've been a Non-Idle Rich; but given L & O's attitude toward the rich, he would've been dirty anyway.
Perhaps he was dirty in Chicago, and came to New York to dodge Internal Affairs.
His way of saying to those complaining about the show's liberal bias, "You think McCoy's a liberal? You ain't seen nothin' yet!"
Detective Briscoe used to be corrupt.
Back in the seventies, he was on the SIU squad under Detective Ciello
. He was prosecuted for corruption, but was acquitted, and remained a detective in the NYPD. All the negative attention, however, drove him to drink. He eventually cleaned up his act, and legally changed his name from Gus Levy to Lenny Briscoe to get away from the ongoing stigma.
The cast of this show got a surprise when Revolution
They found themselves having to get out of the city, and then having to survive the ensuing chaos. Then some of them get the idea that since "law and order" are effectively dead, they can go after all the guilty people who walked away free and make them pay

Briscoe either killed his daughter's killer or had him killed.
If the above theory, that he used to be on the make, holds, then nothing could've stopped him from exacting some street justice. And then there was that phone call during one episode (I forgot the name). Given his reaction upon finding her body, I'd like to think he had something to do with the killer's death. And if your child was killed, wouldn't you want to personally hunt down the monster responsible?
- This one is toyed with, but never fully established (as true or false), in-series. A criminal who owes Briscoe a favor offers to arrange some street justice for him; Briscoe doesn't outright accept but he doesn't immediately refuse either. The killer is dead half a season later, and it's never made clear whether or not that was a coincidence, leaving it up to the viewer.
