The problem with high-profile trials is that you have jurors wanting to be on because it's their moment to interface with fame. They fool themselves into thinking they can be fair.

If both sides get rid of unfavorable people and they wind up with people in the middle, then the verdict will be based on the evidence. If it's done incorrectly, cases can be won or lost during jury selection.

About a week would be more appropriate.

To get this done in one day would be a travesty of justice.
