Caroline Criminal Lawyer, Wisconsin

The burden of proof that the prosecution must carry in a criminal trial to obtain a guilty verdict. Reasonable doubt is sometimes explained as being convinced 'to a moral certainty.' The jury must be convinced that the defendant committed each element of the crime before returning a guilty verdict.

An agreement to do something or to allow something to happen, made with complete knowledge of all relevant facts, such as the risks involved or any available alternatives. For example, a patient may give informed consent to medical treatment only after the healthcare professional has disclosed all possible risks involved in accepting or rejecting the treatment. A healthcare provider or facility may be held responsible for an injury caused by an undisclosed risk. In another context, a person accused of committing a crime cannot give up his constitutional rights--for example, to remain silent or to talk with an attorney--unless and until he has been informed of those rights, usually via the well-known Miranda warnings.

The crime of breaking into and entering a building with the intention to commit a felony. The breaking and entering need not be by force, and the felony need not be theft. For instance, someone would be guilty of burglary if he entered a house through an unlocked door in order to commit a murder.

A peace officer for a particular geographic area -- most often a rural county -- who commonly has the power to serve legal papers, arrest lawbreakers and keep the peace. Depending on the state, a constable may be similar to a marshal or sheriff.

A serious crime (contrasted with misdemeanors and infractions, less serious crimes), usually punishable by a prison term of more than one year or, in some cases, by death. For example, murder, extortion and kidnapping are felonies; a minor fist fight is usually charged as a misdemeanor, and a speeding ticket is generally an infraction.

The killing of one human being by the act or omission of another. The term applies to all such killings, whether criminal or not. Homicide is considered noncriminal in a number of situations, including deaths as the result of war and putting someone to death by the valid sentence of a court. Killing may also be legally justified or excused, as it is in cases of self-defense or when someone is killed by another person who is attempting to prevent a violent felony. Criminal homicide occurs when a person purposely, knowingly, recklessly or negligently causes the death of another. Murder and manslaughter are both examples of criminal homicide.

A crime, less serious than a felony, punishable by no more than one year in jail. Petty theft (of articles worth less than a certain amount), first-time drunk driving and leaving the scene of an accident are all common misdemeanors.

A decision by a judge or jury that a defendant in a criminal case is not guilty of a crime. An acquittal is not a finding of innocence; it is simply a conclusion that the prosecution has not proved its case beyond a reasonable doubt.

A branch of the United States government with power derived directly from the U.S. Constitution. Federal courts decide cases involving the U.S. Constitution, federal law--for example, patents, federal taxes, labor law and federal crimes, such as robbing a federally chartered bank--and cases where the parties are from different states and are involved in a dispute for $75,000 or more.
