TMZ has released "the Conrad Murray video you were never meant to see" -- a secret, emotional recording made days after Michael Jackson died ... in which Murray lies through his teeth about his relationship with the singer, blasts the public for blaming him for MJ's death, and even says he's a victim of MJ's deceptions.

The video -- which was never released -- was shot the very same day Murray recorded the infamous "Do not worry" clip  he released in August 2009 ... his first address to the public after investigators named him as a suspect.

Not only that, but after seven months in prison and three years after Michael Jackson's death, Murray still maintains his innocence. Read that story here.
