Jay is a "Cold Analysis" mofo. He can see repercusions of certain things.
Lemme explain : Jay did not want to be "On Record" saying things he did not control the outcome of.
If he says something on his own album, he has a promotional tour to "play" with the media and rectify/control THE message.

This Ice-T Movie/Doc is an "Indie movie". If it was a major studio release, Jay can call a big wig at the studio and ask them to "edit" the final piece.( And you're asking yourself how can he do it ?)

I don't know the extent of your familiarity with Ice-T hip-hop catalog.But, if you are famialiar with ICE-T catalogue,then you know this next song : http://www.youtube.com/watch?v=bicN4ryVQSI

Okay , see a whole lot of young people think Jay-Z "99 Problems" is an original song.



"And I love 'em all, I love 'em crazily
And they love me back - that's why they stay with me
So if you havin girl problems, I'll be there for you son
I got 99 problems and a bitch ain't one - hit me..."
