“A preliminary hearing is a routine step on the way to a trial. It is one hundred percent the prosecution's show. The state is charged with presenting its case to the court and the judge then rules on whether there is sufficient evidence to take it forward to a jury trial. This isn't the reasonable doubt threshold. Not even close. The judge only has to decide if a preponderance of evidence supports the charges. If so, then the next stop is a full-blown trial.”
