Criminal Law

“I think that being called to the bar of justice is probably one of the most tragic things that can happen to a citizen outside really of a terminal illness. I can’t think of any experience which is more difficult for a person to go through. I have watched people in this courtroom for many years now and it’s a very difficult experience. I mention this and I do at the beginning of ever trial because I want the defendant to know that we are sensitive to his plight.” - Hon. John W. Reynolds, United States District Judge 1/19/1981

Many people and businesses face the prospect of dealing with the tentacles of government investigations and prosecutions. The untrained should recognize that without professional help the match between government and potential defendants is one sided. Handling that situation alone shouldn’t even be an option and attempting to deal with the authorities without proper counsel can make the situation worse and limit your options going forward. Whether you believe that you may be guilty or innocent of a crime, you will need a criminal defense attorney to guide you through the court system, clearly explain your rights and options to ensure that you get the best result possible for your situation.
