INNOCENT until proven guilty or GUILTY until proven innocent?

Presumption of innocence is a legal right. No person shall be considered guilty until finally convicted by a court. In a criminal trial, the burden of proof is on the government. Defendants do not have to prove their innocence. Instead, the government must provide evidence to convince the jury of the defendant’s guilt. The standard of proof in a criminal trial is proof “beyond a reasonable doubt,” which means the evidence must be so strong that there is no reasonable doubt that the defendant committed the crime. Too often, defendants are convicted for crimes they did not commit based on this standard of proof. This is a travesty of justice. Unfortunately, every person that enters our judicial system is a potential victim of that system. Don’t be that victim!
