I have often heard of cases where people who were innocent of any crime, but were convicted because the prosecution used evidence about the personal lives of the defendant to demonize them and make them look like deviants to a jury. Some examples include bizarre clothes, music, friends, internet use, etc. example, the West Memphis Three. I have heard of many cases where a defendant's prior convictions were not allowed to be revealed so why are irrelevant, and prejudicial details about a defendant's personal life often allowed in court? How can you prevent your personal life from being used against you in court?
