Suge Knight, who was riding in the car next to Tupac when he was killed, vows to NOT testify against Keefe D...

From TMZ

Suge Knight is surprised there's finally an arrest in the murder of Tupac Shakur, and even though he was an eyewitness in the case ... he says he'll refuse if called to testify against the suspect, Duane "Keefe D" Davis.

TMZ spoke exclusively with the Death Row Records founder on Monday ... and he insists cops and prosecutors are barking up the wrong tree with their arrest of Davis. Even further, he refutes the long-held belief Davis' late nephew, Orlando Anderson, was the shooter.

Of course, Suge was in the BMW that 1996 night in Las Vegas when both he and Tupac were shot. During the phone call from a CA state prison, he told us regardless of what Davis has confessed to in interviews, or to police ... Suge himself won't ever say a bad word about the man.

He also said prosecutors can forget about getting him on the stand during Davis' murder trial. In a nutshell, Suge says he's not ratting out anyone. Keep in mind, of the 6 people involved in the shooting -- 4 were in the shooter's car -- Suge and Davis are the only 2 still alive.

Cops say Keefe D was in on Tupac's murder and supplied the gun used in the fatal shooting ... which went down shortly after Tupac's crew beat the crap out of Orlando inside the MGM Grand following a Mike Tyson fight.
