Does the FBI know who Biggie's Killer Is?

CBS Los Angeles is shedding new light on the murder of rapper Notorious B.I.G after posting links to newly released FBI files containing information that leads me and many others to believe that not only does the FBI know exactly who killed Biggie but that LAPD members are deeply involved in the murder and cover up.
I read the files and it's quite sad if it is true. According to the FBI's report the case was "thwarted" after an unidentified person uncovered LAPD involement in the murder. The report also says in plain English that they know who killed Biggie, they know that the LAPD assisted in setting the murder up, and that even though they know all of this there is still not enough evidence to convict anybody.
Read the reports here. There is a lot to read but I guarantee it is valuable information.
