This is common and your probation officer may never fill out the paperwork. They are busy and this is often a low priority for them. Most letters written to the judge just get put into the court file. Hiring an attorney would speedy things up. Otherwise keep politely reminding your probation officer. www.BryceFetter.com
It depends on "the bench." There are some judges in Orlando that I would feel comfortable with a bench trial and there are some that I would feel more comfortable with a jury trial. The specific facts of your case and your defense theory also play a major role in making this decision. Good luck. www.BryceFetter.com
Probable cause is a determination made at initial appearance by the initial appearance judge. It is rarely a good idea to say anything at initial appearance. If you have a good case then you can get it dismissed prior to trial or be found not guilty on the merits of the case. Trying to revisit probable cause won't help you now. Even if the judge found no probable cause that does not mean the case is thrown out, just that you are released from jail without having to post a bond.
