Everyone has the right to a fair trial.

Anybody else feel slightly uncomfortable at the way the trial of the man accused of abducting and murdering April Jones is being conducted?  The jury were played a recording of the 999 call made by her mother - why?  They were taken on a day trip to Machynlleth where the incident is alleged to have taken place - why?  They have been read statements by April's mother and father telling of their frantic efforts to search for her - why?  How do hearing or seeing any of these things make it more or less likely that the accused man is guilty?  Where is the relevance? What subjecting the jury to this information is likely to do is play on their emotions and make them more sympathetic to the prosecution's case - in other words it is prejudicial to the accused.  So why was it allowed?
