Not if you make up your mind now. Go guilty just for shits and giggles. That will show em 😁
Now, you joke, but when I did mine, after sitting around for a day and a half got called for the selection process. At this point you see the defendants, to avoid the mentioned issue of knowing them. I took one look and though guilty as fuck - I doubt very much anything in the case would then shift that view (they just looked it). Fortunately I wasn't selected, got sent home that day and never called back in.
