Los Angeles Superior Court Judge Keith L. Schwartz set Dr. Conrad Murray's bail at $75,000, three times the amount normally asked of those charged with that type of crime.
  

"Involuntary manslaughter was the smartest move for the [District Attorney] to make," said Loyola Marymount law professor, Stan Goldman. "All they have to prove is that [Murray] was criminally negligent in his behavior when he gave Jackson the drugs that led to his death."
  

Involuntary manslaughter is the least serious homicide charge prosecutors can bring forward. To prove anything more, explained Goldman, the D.A. would have to show the doctor knowingly risked Jackson's life when he administered the drugs but did it anyway.
  

Some of Jackson's fans who gathered at the courthouse near Los Angeles International Airport, where Murray pled not guilty, deemed the involuntary manslaughter charge insufficient. The charge could carry up to a four-year state prison sentence.
  

"They're treating [Murray] with kid gloves," said Betty Byrnes while she held up a "Justice 4 Michael" sign. "This man committed murder, homicide, and he should be arrested. Any other citizen would be shackled in handcuffs and put away by now." 

Other fans said they share no hostility toward the doctor. 

"We're here for love. We're not here for negativity or against Murray," said President of the Micheal Jackson's Southern California club, Heidi Heidel. Her and other club members sported red arm bands as a sign of unity for the Jackson family. They leave cards and flowers from "around the world" at the pop singer's cemetery on the third of every month so "Michael will know he's not alone."
  

Jackson's family--including his mother, father, sister La Toya, and brother Randy, also showed up to the courthouse near LAX. Joseph Jackson, Michael's father, only said, "We're looking for justice," when asked whether he was satisfied with the charges. 
  

Dr. Murray, a cardiologist, was expected to surrender to authorities Friday, but his appearance was canceled after Murray's attorney charged authorities of using the event as a "photo op."  The D.A.'s Office and the Los Angeles Police Department denied the accusation.

Murray has been the center of a seven-month investigation launched after Jackson's death.  Murray served as Jackson's personal physician while the singer prepared for a comeback last summer that included a 50-concert series at London's O2 arena. 

His attorney, Ed Chernoff, has denied any wrongdoing by his client, insisting Murray never gave Jackson anything that should have caused his death.
 

Murray told investigators he gave Jackson sedatives to help him sleep, but admitted the singer may have started becoming addicted to the drugs. He said he had been trying to wean Jackson of them. 
  

The doctor's cocktail that allegedly killed Jackson included Valium, followed by Lorazepam and Midazolam before he finally administered Propofal (Diprivan) diluted with Lidocaine, according to the affidavit. Prosecutors are expected to focus on the doctor's use of Propofal to cure Jackson's insomnia; the drug is usually administered by anesthesiologists for major surgery. 
 

The Los Angeles County's coroner's office did determine the Propofol to be the ultimate cause of Jackson's death. 
  

After Murray gave Jackson the drugs, Murray said he left the pop singer unattended for a couple minutes while going to the bathroom. But, based on cell phone records, investigators think he left Jackson alone in his bedroom for up to 45 minutes.
  

Jackson, 50, was found unresponsive in his bedroom at a rented estate in Holmby Hills before he was rushed to Ronald Reagan UCLA Medical Center. He was pronounced dead about 2 p.m. June 25th.
