Every criminal defendant is guaranteed to have legal representation, no matter his or her economic status.  If you have been arrested, think back to your Miranda Rights.  "If you cannot afford an attorney, one will be appointed to you."  This representation is provided by the government, and it is referred to as a public defender.  If you are able, you are entitled to hire your own lawyer to represent you through your criminal proceedings. 

This representation begins as soon as you contact your attorney.  You may have an attorney assist you during questioning at the police station, as well as throughout the entire criminal procedure – from the time of your arrest, through your conviction or acquittal, and throughout any appellate process.  Furthermore, he or she is required to represent you in the best manner possible.  

Instead of suing or defending people for money damages, a criminal law attorney instead works to prevent his or her clients from spending time in prison, serving probation periods, and paying fines issued from the state.  One important note to remember though is that one's crimes he or she commits can sometimes also lead to civil damages.  In this case, if the incident involves another individual, a separate civil lawsuit is brought. 

An example would include a drunk driver running over and killing a pedestrian in a crosswalk.  This driver, if convicted to the fullest extent, would likely go to jail.  In addition, the victim's estate may choose to sue the driver for money damages as well.  Some attorneys will handle both the criminal and the civil claims.  If you are looking for an attorney skilled in both aspects, then ask him or her during your consult.
