You’ve almost certainly heard the phrase “guilty beyond a reasonable doubt,” but have you ever thought about the specific meaning of “reasonable doubt?” As an American, you should. That’s because this phrase is a cornerstone of our national justice system. Rather than some countries that consider you guilty until you are proven innocent, the American constitution allows criminal suspects the privilege of being innocent until proven guilty. In addition, that guilt needs to be proven beyond a reasonable doubt. Because the burden of proof is on the prosecution, a criminal defense attorney must only show the jury that the prosecution does not have enough evidence to undoubtedly prove the defendant is guilty.
What is Reasonable Doubt?
The concept of reasonable doubt is one of the most powerful weapons on the side of all defense lawyers because it means that the simple fact that charges have been filed against someone does not serve as evidence against them. In practice, the definition of proof beyond a reasonable doubt is when the prosecution has provided jurors in a criminal trial with enough evidence that they are left with an abiding conviction that the charge against the defendant is true despite the contradictory evidence presented on the defendant’s behalf.
Some Doubt May Remain
Although some people believe that the standard of reasonable doubt means there cannot be a question in the mind of the members of the jury, that is not true. After all, few things in this world are black and white, and many people who serve on a jury will question their ultimate decision at some point or another, no matter how convincing the evidence is in the case. The evidence need not eliminate all possible doubt because everything in life is open to some possible or imaginary doubt.
However, if jurors base their decision on the standard set by the American justice system, then they cannot find the defendant guilty unless they are utterly convinced. This high standard of proof ensures that most jurors will not look back on their decision and regret sending an innocent person to prison.
Even a Seed of Doubt is Enough
Because reasonable doubt is the highest legal standard for a trial, the prosecution must sufficiently prove the defendant’s guilt in the jury’s mind. Even if the prosecution proves the defendant to be mostly guilty but the defense attorneys create a good seed of doubt in the juror’s minds, the defendant should still be found innocent because the evidence is not enough to quell all reasonable questions of the jurors.
