Former gangster 'Mob James' refuses to rat out old enemy in Tupac Shakur murder trial

A notorious former gangbanger scoffed at lawyers asking him about Tupac Shakur's murder — daring the court to "treat me as a hostile witness" in fiery testimony on Tuesday.

"Mob James" McDonald — former member of Compton's Mob Piru Gang and private muscle for Death Row Records — scoffed at lawyers on both sides who peppered him with questions about the gang war that led to the rapper's 1996 murder on the Las Vegas Strip.

"I'm aware of a lot of things. Things that was going on. People ain't talked about it in 30 years. Today ain't one of them," McDonald said as the prosecution attempted to tie the now 63-year-old Duane "Keffe D" Davis — of the rival South Side Compton Crips gang — to the murder plot.

"Me or anybody else raising up the dead is wrong," McDonald said when asked to talk about the 30-year-old beef.

"I don't want to send [Davis] to prison. Even though we don't like each other," McDonald declared before ripping the court for forcing him to dredge up memories of the old life he wants to put behind him and protect his grandchildren from.

Prosecutors say Davis gave a gun to his nephew Orlando Anderson and told him to shoot Shakur as an "act of revenge" after the rapper and his pals beat Anderson up.

The testimony ended in a shouting match with McDonald throwing up his hands and saying "I'm not answering nothing. I don't know what you're talking about."

Then, turning to Davis, he said: "Cover your lawyer, man. That dude is trippin.'"

"I'm not gonna send him to prison. You are," he said of his old enemy.
