I just don't understand why Paul Walker's character faked his death at the end of Running Scared.
I did some research online and there's an answer that says that he's a rat and was put in WITSEC?
He's obviously not a rat because he said in the movie:
I was undercover for 12 years and my wife doesn't even know about it.
So I guess the term "undercover" doesn't apply for rats right?
