At a trial 12 people who live in your area (the Jury) will listen to the evidence that the prosecuting attorney presents (that says you did it) and that your attorney presents (that says you didn't do it!). Then they decide whether the prosecutor has proved that you did it.

The prosecutor has to prove that you did it, but you are presumed innocent (that's another one of your constitutional rights) - that means that, unless the prosecutor has enough evidence to show the jury beyond a reasonable doubt that you did it, then you get to go free.

Here's how the trial goes: first, the attorneys pick 12 people to act as the JURY from a big group of people who came to the courthouse to be a jury. That's called "voir dire" (vwah deer).

Then the attorneys tell the jury what they think the evidence will prove. That's called "opening statement."

Then the prosecutor presents the evidence to prove you did what they said you did - it can be testimony (people talking about what they saw or heard) or physical evidence (things like finger prints or clothing found at the scene of the crime).
