In Chandler v. Florida the Supreme Court ruled that a state could permit broadcast and still photography coverage of criminal proceedings, since cameras and microphones in the courtroom were no longer an inherent violation of a defendant's 14th Amendment rights, as opposed to the earlier ruling in Estes v. Texas . Moore explains, "in Chandler two men were convicted of conspiracy to commit burglary, grand larceny, and possession of burglary tools after they were charged with breaking and entering a popular Miami Beach restaurant. (Both were Miami Beach police officers at the time of their arrests.) The trial attracted considerable media attention; cameras were in the courtroom, as permitted under experimental Florida Supreme Court rules (Moore, p. 452)."
Nowadays, nearly all states and even the federal courts allow cameras in the courtroom, with only limited restrictions. Since the cable network Court TV started broadcasting in the early '90s, there seem to be no major complaints of lack of due process or sensationalism.
