His critics called Jackson out for appearing to be above the law. Celebrities are protected and have top lawyers and appear to be above the law and they can get away with a lot more things than the normal citizens of this world. Celebrities get lighter sentences or get off for crimes that anyone else would get prison time.
Despite the top laywers he had, he couldn't avoid the humiliating investigation, part of which was the photograph of his genitals and moreover the court in 2005. Being a celebrity means nothing. You 're not above the law, you are not protected. Jackson was acquited because the court find no sign of his behaviour, hidind any sexual act against under age children. Simple as that.
