My question involves criminal law for the state of: Florida

Hi,

My arraignment is around the corner, on Wednesday March 14 2012, for Orange County, Florida.

I am 18 years old, and turned 18 only a week before I was arrested, therefore I am considered an adult. It was my first offense, no prior criminal record. The merchandise was valued @ 40$(two shirts under my own shirt). I am currently a senior in high school.

Can someone PLEASE explain or give me an outline on what will happen when I reach the court? I am going alone and my parents don't know yet. What should I do? I know to plead not guilty. Also am I entitled to a public defender?

If I am offered the pretrial diversion program, what is the program like and what am I supposed to do in it?

The cop also told me that I will have my adjudication withheld? <- can I still try to get my charges expunged/dropped after a year? or only sealed?
