You could wait until the trial, after getting the free lunch, and then see what ethnic group the person on trial is then exclaim just loudly enough to be sure it gets overheard, 'lets get this *insert ethnic slur appropriate to ethnic group of defendent* sent down' or 'we need to stick up for our fellow...' either one should get yourself disqualified.
Although if its a drugs trial and the defendent hasn't been violent, stick with it and give a not guilty verdict regardless of the circumstances, since the US judicial system is massively biased against such people and the DEA twist everything in their favour if they can. And such people shouldn't be in court anyway. For example, if someone were caught with LSD, which is dosed in the microgram range, the entire weight of the carrier (that is, the paper, or gelatine its contained in in windowpanes, or inert tablet binders for microdots) is classed as weight of the drug when sentencing is considered, so someone caught with enough PAPER to weigh 1g (which would be a rather large quantity of pure LSD) would get sentenced not for the few milligrams of acid on the blotters but for the entire weight of the inert backing, which would get treated as if it too were the drug itself) same goes for inert cutting agents and people end up doing time way out of proportion to what they actually had. Not that they should be in court in the first place, let alone doing time.
