well, the southside crips had already been beefing with the mob piru's (your usual compton turf shit). it just spilled over into vegas because both groups had a "violate on site" policy.
now, heres where it gets tricky. p diddy has historically been close to demetrius fleneroy (big meech-founder of the black mafia family). the bmf syndicate had a unit that operated out of the southside of compton. was this the same crew that fought the mob piru's from 95-98? who knows. but the connections are there.
also, p diddy was born into the combs crime family. his father was duke combs, close partners to nickey barnes and frank lucas. his cousin (last name combs) was an associate and possibly a member of bmf. he snitched a few years back for a lighter sentence. diddy also grew up with and retains a good relationship with gambino family capo andrew campos. so in other words, diddy is black mob royalty by birthright, irregardless of if he is directly involved or not. so it is not inconceivable that he can get someone touched. and probably for much less than a milli.
