That's why it's imparative to as best they can, get an impartial jury. I'll bet even an impartial one starts forming an opinion during opening statements. If not, why would opening statements be so important? Repetition is also essential. If you repeat something, even a lie so many times, people will start to use it as a base of reference. Then later, if they're told it's a lie, they don't believe it.
I'll take a really silly example and give you. That Michael Jackson song, "smooth criminal." All these years, I thought Mike was saying "Eddie, are you okay? Eddie, are you okay? Are you okay, Eddie?" So did many people that I know. Well, I was reading the lyrics off it when it was one some dance game my nieces were playing on their Wii. And he really says, "Annie, are you okay. Annie, are you okay? Are you okay, Annie?'
I didn't believe it. I had my sister look it up on the internet. There it was "Annie, are you okay?" I still didn't believe it. I was so disappointed, because it changed the WHOLE meaning of the song for me. Now I have to consider that the song is about the murder of Annie instead of about some gangster named Eddie.
OMG. I just realized this song sounds like this case. I'm so serious, I just made the connection as I was typing. I'm EVEN MORE disillusoned because this song will now forever remind me of MK.
