Ogletree, who organized the discussion, said he had no reservations about inviting contentious figures to this, one of HLS's "Saturday School" panels.

Before the panel, Sharpton, Koch and Ogletree presented the program to leaders of the state legislature. They will soon present it to Attorney General Janet Reno and the Congressional Black Caucus.
