Dr. Conrad Murray exclusive smiling michael jackson trial death

What murder trial?

Considering he's about to face manslaughter charges for the death of Michael Jackson, Dr. Conrad Murray looked surprisingly calm as he strolled through Santa Monica with his family on Wednesday.

But the doctor, who allegedly gave the King of Pop a lethal injection of Propofol on the day he died, may not have to worry about jail when the case goes to trial next week. If Murray is convicted of INvoluntary manslaughter, he could avoid state prison all together.

It's up to Judge Michael Pastor to decide whether Murray should be sentenced to probation, or serve his time (four years max) in a Los Angeles County jail.

Jury selection resumes on Friday and opening statements begin Sept. 27.
