Ice-T

Ice-T(neé Tracy Lauren Marrow) is a famous rapper/actor/ex-pimp(jep!) who certainly is worth checking out on. One of the founders of the socalled gangsta rap(back when that meant something) Ice-T really got in the public eye, when following the killing of Tupac Shakur and the riots in L.A., he made a (very good) song titled "Cop Killer". The lapd did not respond graciously.

This description makes Ice-T sound very controversial, but he tends to be wonderfully consistent and clearspoken; this man finds the message more important than the shock effect.
The complexity of his character is for instance to be seen in his playing the part of Detective Fin Tutuola in the show Law & Order: Special Victims Unit, which as far as I'm informed is about the only show of its kind, and a very good one at that.

I would like to recommend checking out Ice-T and bodycount on youtube, especially, cop killer, born dead and the winner loses.

Finally some quotes from the man himself:

So you don't have to take us too seriously; I mean, we're already intimidating enough on stage.

The Constitution is a figment of your imagination, held up to make people believe they have rights. I don't believe anybody in this country has rights

You can't come out on a record dissing the system and be on a label that's connected to the system.
