>> phillips believed michael had a very personal reason for taking on the scheduled 50 concerts. >> i said, why now? because i had been chasing him to come out of retirement and get on the stage and perform live for three years. this was, you know, like a mission of mine. a quest. and he said to me, very interesting, was very poignant, he said, "i'm doing it now because my kids are old enough to appreciate what i do." >> michael's children have played a major role in this case. his oldest son, prince, took the stand in june. >> prince jackson made an impact on the jury, perhaps most importantly in humanizing the loss of michael jackson as a father. he described the life, the birthday parties. he described the fun, and he described the sadness. and the jury listened very closely. >> the kids saw their father as he lay lifeless in his bedroom.
