Defenses to Criminal Charges

Defenses to Criminal Charges To convict a criminal defendant, the prosecutor must prove the defendant guilty beyond a reasonable doubt. As part of this process, the defendant is given an opportunity to present a defense. There are many types of defenses, from "I didn't do it" to "I did it, but I was too drunk to know what I was doing." Here are some of the most common defenses that criminal defendants can raise.

The Defendant Didn't Do It

Most often defendants try to avoid punishment by claiming they did not commit the act in question.

The Presumption of Innocence

All people accused of a crime are legally presumed to be innocent until they are convicted, either in a trial or as a result of pleading guilty. This presumption means not only that the prosecutor must convince the jury of the defendant's guilt, but also that the defendant need not say or do anything in his own defense. A defendant may simply remain silent, not present any witnesses, and argue that the prosecutor failed to prove his or her case. If the prosecutor can't convince the jury that the defendant is guilty, the defendant goes free.

Reasonable Doubt

The prosecutor must convince the judge or jury hearing the case that the defendant is guilty "beyond a reasonable doubt." This standard is very hard to meet. As a practical matter, the high burden of proof in criminal cases means that judges and jurors are supposed to resolve all doubts about the meaning of the evidence in favor of the defendant. With such a high standard imposed on the prosecutor, a defendant's most common defense is often to argue that there is in fact reasonable doubt.

The Alibi Defense

An alibi defense consists of evidence that a defendant was somewhere other than the scene of the crime at the time it was committed. For example, assume that Freddie is accused of committing a burglary on Elm Street at midnight on Friday, September 13. Freddie's alibi defense might consist of testimony that at the time of the burglary, Freddie was watching Casablanca at the Maple Street Cinema.
