Lawyers for both sides today will begin paring down a group of 40 prospective jurors to a final group of six jurors and four alternates.

In Florida, 12 jurors are required only for criminal trials involving capital cases, when the death penalty is being considered.

In the first round, lawyers were only able to ask potential jurors about their knowledge of the case gleaned through the media and other means. In the second round, attorneys can ask a much broader array of questions regarding what they think about the case.

Zimmerman is charged with second-degree murder in the death of 17-year-old Trayvon Martin. Zimmerman is pleading not guilty, claiming he acted in self-defense.
