Dr. Murray Prosecutor Conrad Should've Stayed AWAY from 'Today' Show

Dr. Conrad Murray
NEVER should have agreed to be interview by "Today" ... because the "complete lack of remorse" he demonstrated on the show made him look even more guilty ... this according to the rock star attorney who prosecuted the doc.

Deputy District Attorney David Walgren appeared on "Today" this morning -- and said Murray showed a "complete lack of personal responsibility" in an interview with co-host Savannah Guthrie that aired days after the conviction ... insisting there's no way it could've helped Murray's case.

Murray was all over the place during the interview -- contradicting the story he originally told police and then proclaiming, "I didn't do anything wrong!"
