A Question of Trust as the Other

To all my adoring fans out there, sorry this is late. Had some weird Yahoo/Google issues going on as far as gettin' here. Anyhoo, we're still talkin' Othello (although I know not in what regard) so that is once again my subject.
I'm doing a little presentation for a class assignment where we enact various scenes from selected Will S. works. Of course, I'm in the Othello group. I am Othello (said in a deep, dramatic voice).
Our learned director (and classmate) felt inclined to update this classic w/a contemporary twist which is cool. However, I am hard pressed to determine how I should portray such a complex character as Othello.
Our group has chosen to give the work a Law and Order energy. I'm Homicide Division Capt. O. Thello (cute, eh?). I am head honcho and thus control the destiny of one Junior Detective Iago, much the same as in the original work. Now, here's where it gets sticky.
As in the play, I am the Other. Here, I am a brown-skinned, female in a male controlled world. I am the leader of men and women, who is respected, served, and yet manipulated by another's hatred and jealousy. I give my trust freely only to have it corrupted by deception. In the end, I fall to these lies and my naive trusting of the world around me.
Was Othello naive? I believe so. Wanting so much to fit into a world which only used him left him blind to the potential for attack. He trusted too freely. But what could he have done? Not only words but proofs presented enriched the poisons being dripped into his ear. Maybe there was nothing he could have done to avoid his downfall. Besides, Iago was just too slick in his maneuverings.
That said, I guess there is only one thing left for me to do. I must play the role of naive, trusting fool as it is presented. I am the leader - proud of my position and determined to give the best service I can to my superiors. All the while, there is a dagger aimed at my back of which I am unaware. My naivety, in fact, pushes the dagger through my flesh deep into the muscle within. I will fall and take others with me and as I go, what lesson have I learned in my final hour? That my trust of a world, in which I could have never really been a complete part of, was my doom.
