Yachar koach in assisting the country in fulfilling a Noahide mitzva of providing justice.
In my personal experience, I was surprised to be the most liberal member of the jury while judging a possible drunk driver on an empty street at night who possibly did not speak English… While for me, drunk driving is just a bad thing to do, many others had personal experiences with misbehavior and loss in their communities and wanted to be as strict as Beit Shammai ever was. One self-identified as a pedestrian and simply hated all drivers who did not stop in front of her.
My last argument in favor of rahmonus was – that the person might be in some immigration status where he would be deported based on this very minor crime, and who knows whether he is also supporting a family. Nobody cared.
