Jermaine Jackson
isn't just furious that Conrad Murray is a free man -- just 2 years after Murray was convicted of manslaughter -- Jermaine is "disgusted."
Michael's bro expressed his ire moments ago at LAX, but you really have to watch the video to get a feel for it.
Randy Jackson was also there, but he was feeling a little less talkative.
As we reported, Murray was released from jail in L.A. early this AM ... and immediately hit up an In-N-Out for some burger therapy .
