Are you thinking of Lynn Stewart the lawyer for Sheik Abdel-Rahman who was convicted in a thwarted conspiracy to assassinate Egyptian President Hosni Mubarak and bomb New York City landmarks, including the United Nations and bridges and tunnels.

I wonder if she has ever been tried yet. Or is she free on a bond and still being a home grown terrorist.
Ask and ye shall receive. US lawyer Lynn Stewart to be tried for helping terrorist group
