'Poor Conrad Murray ...'
Prosecutor David Walgren is attacking with sarcasm in his closing statement rebuttal ... telling the jury, "Poor Conrad Murray ... everyone is just working against him."
Walgren says Dr. Murray's treatment of Michael Jackson was littered with, "bizarre, unethical, unconscionable behavior" ... adding, "That is why we are here."
Walgren says the defense team is blaming EVERYONE but the doc -- mocking the defense for suggesting a "conspiracy" against the doctor.
"Everyone's to blame but Conrad Murray ... poor Conrad Murray."
