There are some scary people on here, really scary.
A Juror is a very important part of our justice system, and in many ways that is what makes our justice system different than what they have in other places.
A Juror has a specific job to do, firstly a juror must be neutral, and should go into deliberation with no malice or affection towards the accused or the accuser. A Juror isn't an investigator, anything found online is useless to an impartial juror as it cannot be deemed authentic or valid. All a juror should ever take into account is the evidence and testimony they observed in court, nothing more, nothing less. The prosecution has their chance to present evidence and testimony, as does the defense, they can and do produce everything they want to, everything they feel is relevant. The juror must ignore any outside information not presented in the courtroom during the trial.
No, I would not go online and pervert the justice system, as a juror it isn't your job or place to, if the defense could not persuade you that the accusations were false, that is how it goes, if the prosecution couldn't convince you the accused is guilty, he isn't, and that is the end of it.
If you want to be an investigator there is no end to the opportunities for you, the police need good investigators, most good lawyers have relationships with private investigators, if that is your thing go for it, but please don't take it upon yourself to play Perry Mason when another persons life and freedom are on the line, follow instructions, do your job honestly and fairly.
