Another day of drama ensued at a Santa Maria courtroom today as Michael Jackson again arrived late for trial.

Jackson appeared to be in pain as he shuffled into the courthouse just after 8:30am PT. After eventually making it to his seat some ten minutes later, Jackson then almost immediately got up to leave. Pool reporters described Jackson as "shaking and sobbing," and "appearing as if he might vomit."

After a 45 minute delay, testimony resumed with Jackson's doctor sitting behind him.

So far, no explanation has been forthcoming for Jackson's behaviour today.
