First Time Watching - Jake's an Undercover Cop, Right?
I'm at the part where Alonzo takes Jake to that man's house (with Dr. Dre and crew) -- this is about half way through the movie. They've just carved out a piece in the wooden floor and have discovered some kind of *treasure chest.* Jake is not taking any of it, despite Alonzo's offering and the other guys taking some for themselves. But, I'm watching carefully and thinking... Jake has to be some undercover cop playing the good guy role.
In the first few seconds of the movie, the camera catches a shot of what looks to be a home-made altar with Jake's photo at the center, as if he has already died. This is why I'm sure he's not exactly who he seems to be to Alonzo. His wife knows. He knows. He's in it as an undercover cop sent in to bust Alonzo's corrupt operations within the L.A.P.D., right???
