Just some clarification for those readers not in the U.S.. You as the defendant do not have to select have your case tried by a jury. You can select to have a bench trial instead. There is a presumption of innocence for the defendant, so the prosecutor has to show "beyond a reasonable doubt" that the defendant committed the crime in question. Juries find defendants not guilty more often then judges do. So if you want a society that better reflects the maxim, "better 10 guilty men go free, than 1 innocent man go to prison", then juries are empirically better.
Even if you ask for a bench trial, the state can request a jury trial on your behalf since the presumption in law is that juries are objectively better.
