In a move that is completely legal, superstar Mary J. Blige filed a lawsuit in a Manhattan courtroom against street vendors who plan to sell bootlegged t-shirts and other tour memorabilia outside her concert tomorrow.
She can do that because of a law allowing people to sue "Jane Does" and "John Does" who will be named at a later date. Mary and Jay Z are set to perform a sold out show at NY's Coliseum tomorrow night.
"She is suing John Does and Jane Does numbered 1 though 100, so law enforcement can confiscate the bogus stuff as they are selling it. They are sued under fictitious names because their true names are unknown at this time." (Source)
