Criminal law is considered much more complex than any other law. Criminal law involves prosecution of a person for an act that is classified as a crime by the government. In a criminal case, the state initiates the case against the person concerned. Criminal laws include felonies and misdemeanors. A crime is any act in violation of a public law forbidding it. (A crime can also be an omission of an act when public law actually requires it.)

Felonies are punishable by a prison term of more than a year, while misdemeanors are punishable by a prison term of less than a year. Criminal laws differ from state to state.

Therefore, it is necessary to have an experienced and competent criminal lawyer on ones side. Good criminal lawyers can represent anyone committed with a crime and can negotiate to arrange for lesser sentencing or reduced charges.

A competent criminal lawyer formulates sentencing programs, which are most preferable for the client's specific needs. Defendants will be provided with a knowledgeable, unprejudiced and objective over view of their case. This overview plays an important role in the defendant's decision whether to go into a plea bargain.

Good criminal lawyers are well versed with the important legal rules and also familiar with the various court customs and procedures. The also have the skill to understand the 'hidden costs' in a plea bargain. They also garner some information from the prosecution witnesses.

Statutes regarding criminal behavior can be broken down into various elements. Generally, most crimes have two elements, the action and the mental state. Each and every element of the crime should be proved, before the prosecution can come to a proper decision.
