Dr. Conrad Murray must have some pretty thick skin -- because sources close to the doc tell TMZ he's "not at all upset" with the people who were calling him a "murderer" on the way out of court yesterday.
We're told Doc Murray believes that everyone has a right to express their feelings ... even if he doesn't agree.
As we previously reported, several Michael Jackson supporters hurled insults at the doc as he left an L.A. courtroom yesterday ... right after Murray's legal team was granted access to MJ's fluid samples to aid in his defense in the involuntary manslaughter trial.
A rep for Murray's defense team tells us, "We're just happy there wasn't a blimp this time."
Dr. Conrad Murray -- No Hard Feelings
