I'm and for some reason i think Michael's family is tired of this whole disguise of manslaughter charges to protect Dr. Murray from getting murder charges.
Dr. Conrad Murray knew exactly what he was doing when he gave all the amount of drugs he gave to Michael Jackson, he knew that giving a frail Michael Jackson all those prescription drugs mixed up PLUS the anesthesia Propofol will caused the unevitable and asured death of Michael Jackson.
Now Dr. Murray had(or he thought he had) the perfect excuse to scape the murder charges and be only charged with manslaughter which he thinks he's gonna scape, BUT HE THOUGHT IT WRONG! let me explain exactly what Murray thought as his perfect alliby, he knew Michael Jackson was adiccted to prescription drugs and Propofol, he thought that that very addiction would be his perfect excuse, he would said he was getting aware of his patient addiction on the curse, that he was not aware of it and he would say he tried to help him by giving him a lower dose of Propofol, cause Dr. Murray was so innocent that he would give Michael whatever Michael wanted (he was well aware of MJ's addiction, but he of course claims he didnt know Michael had those problems, poor helpless little innocent lamb dr. Murray), so he will make it look like an accidental overdose which is a BIG FAT LIE; cause here comes the big aweful truth, he knew Michael would die, he carefully prepared everything to make it look like some kind of accident he alledgedly never expected to happen, and that is exactly what will gave him MURDER CHARGES!, HE GAVE ALL THE WRONG DRUGS AND HE MIXED THEM IN PURPOSE, KNOWING EXACTLY WHAT WOULD HAPPEN which is of course MICHAEL'S DEATH, THE MOTIVE IS, WELL, VERY SIMPLE, MONEY, SOMEONE IS BEHIND MURRAY, SOMEONE IS SECRETLY SUPPORTING MURRAY, SOMEONE PAID HIM TO DO THIS, THIS WAS CLEARLY MURDER, THERES NO OTHER EXPLANATION AS FOR WHY A DOCTOR WOULD GIVE SUCH LETHAL AMOUNT OF DRUGS ALL MIXED UP AND ADDING PROPOFOL TO SOMEONE WITHOUT NOT KNOWING IT WILL CAUSE DEATH. Who that one supporting Murray is, well that would give the final ending to this case, and is Police work, they will unfold this lie, Michael Jackson was killed on purpose.
