Except I have done jury duty once for a DUI.
First, you don't have to do a field sobriety test. Second they are a scam by the cops to make evidence against you when they don't have any.
When I did jury duty, they had a man whom they told to walk 7 paces, turn around, and walk 7 paces back, so he starts, and then the officer said, "I didn't tell you to begin, so that's a fail. Do you want to re-do it?" The guy said, "sure." The cop said, "Begin." The man begins, turns around and comes back right on the line. The cop then arrested the man saying he had given him more chances than he needs and he failed because he didn't wait to listen to the instruction to turn around as if it is some fucking game of simon says. Not to mention, they never gave him ANY instruction that he has to wait to be told to turn around.
At any rate, the prosecutor went on and on, and we watched the video. After the video, I stood up as a juror and said, "I have already decided he isn't guilty and won't change my mind. It takes only one (1) not-guilty, so let's end it here." The judge told me to shut-up only officers of the court can speak up. I told him that I AM an officer of the court. He said, "you haven't even heard the jury instructions." I responded, "I don't need to hear them." The judge then asked, "Is there any reason I should not kick you off the jury?" I responded, "because I am making an informed decision, and if you do, I am going to file a motion in the Court of Common Pleas that I was a jury and discharged from service for not rendering a decision the court agreed with.
The judge dismissed us all telling us not to discuss the case. Then about 10 minutes later, we are told the prosecution dismissed the case.
