Honestly, the jury selection process is stupid. It depends on people to either live under a rock, or to lie about their character. Our jurors should be informed on the world and have opinions. Fairness achieved through witless conformity is justice by committee.

If we want better trials, getting rid of one-sided testimonials like the grand jury process, would be a much better way. It is weird how prosecutors get to put forward only their viewpoint, while the defense can't. Randomly splitting the jury in half to listen to the defense and prosecution's argument, then having each half hear the other side's story, would be a better approach IMO. That removes the first-mover advantage to story telling. Also, a 20 minute snack and drink break for each session, to remove grouchiness as a factor.
