It wasn't even a full on diss on 'Bomb First' it's just that like Tupac said, he was doing business when he was rapping, he was trying to make money, get power, make changes & live the good life while Xzibit's talking about doing it for the music. As the Outlawz were meant to hold the same principles as Tupac, Edi name-checked him for something they must've felt was bullshit. But it's nowhere near hate, just a minor diss for that instance & nothing more.
And for he who said that it was because of Ice Cube - read up or stfu.
As for the paparazzi line, wasn't 2Pac spitting at cameras & shit? Yes he was. He wasn't too keen on the media & I think that's what he was expressing when he spit that line on 'All Out'.
