Michael Jackson's doctor Conrad Murray, said he took all necessary precautions when he treated Jackson, in a recording that was played to jurors at his trial on Friday.
As the Los Angeles Times reports, Murray spoke to two detectives in the recording. He attempted to explain the names of the drugs he gave to the pop star. He said he tried, without success, to get Jackson to sleep after prescribing multiple drugs besides propofol, the one that eventually killed him.
