WHY? Because her effing brother died under Conrad Murray's WATCH FOR GODS SAKE!.
This is not just a Janet thing this is a Jackson thing, all of these ungrateful people hesitate in stating Murray is responsible. Karma us gonna hit them hard due to the despicable nature of their behavior, that's for damn sure.
Usually relatives of a victim wouldn't stop screaming from the top of their lungs that this guy is responsible while demanding justice to be done, but not these people, no, - they rather help let the killer of their relative/sibling/son walk free - by giving ambiguous statements to the press and posting cryptic posts on Twitter- as long as they get a pay check from a third party with money and/or are able to promote themselves and their products with fake ass intervention stories.
Their craving for money and fame/success by all means will sooner or later backfire on them big time. And I will be happy to watch them fall on their big mouths.
