What is the impact of the news media on the integrity of a jury trial?

"When a spectacular crime has aroused community attention and a suspect has been arrested, the possibility of an unfair trial may originate in widespread publicity describing facts, statements and circumstances which tend to create a belief in his guilt. [p] Indispensable to any morally acceptable system of criminal justice is a verdict based upon evidence and argument received in open court, not from outside sources. [Fn. omitted.] When community attention is focused upon the suspect of a spectacular crime, the news media's dissemination of incriminatory circumstances sharply threatens the integrity of the coming trial.... [p] The goal of a fair trial in the locality of the crime is practically unattainable when the jury panel has been bathed in streams of circumstantial incrimination flowing from the news media. [Fn. omitted.] ... An honest juror may admit knowledge or tentative prejudgment and find himself excluded. Many will sincerely try to set aside [232 Cal.App.3d 802] their preconceptions and give assurance of impartiality, yet unconsciously bend to the influence of initial impressions gained from the news media. [Fn. omitted.]" (Corona v. Superior Court (1972) 24 Cal.App.3d 872, 877, 101 Cal.Rptr. 411.)
