It’s against the legal code of conduct for a DA to make public statements which can affect the impartiality of the jury pool.
Basically, a prosecutor has to keep his/her mouth shut, and save it for the trial.
We learned (or didn’t learn) the damage a DA can do by watching Nifong prep a lynch mob.
Don’t they have rules of conduct in Florida?
Or did Nifong move there and start giving lessons?
The DA in this case doesn't have to. He has surrogates in the form of Crump, Parks, and Jackson who are in touch with him daily and do all of that for him. Crump is the state's unofficial mouthpiece.
