The Supreme Court recently held in Chandler v. Florida, that absent a showing of actual prejudice, it is not per se unconstitutional to televise trials over the objection of the defendant. This decision has a direct bearing on state court procedures, as over one-half of the states currently permit television coverage of trials in one form or another. However, sheer numbers supporting a proposition do not make that proposition "right", nor does a Supreme Court decision upholding its constitutionality imply an unqualified stamp of approval. In fact, previous Supreme Court decisions have overturned convictions because the defendant's right to a fair trial had been violated as a result of media coverage of his case.
