If you commit a crime, you will be prosecuted and tried by a State Court, unless you committed a crime punishable by a Federal statute.
Federal offenses have very severe sentencing guidelines. Moreover, over 90% of the federal criminal cases result in a conviction.
A Federal Defense Lawyer in New York can help you protect your rights since the day at the arrest to the jury trial. The fact that you have been arrested and charged with a crime does not mean automatically that you are guilty.
Before trial the Federal Government will have to disclose all the evidence that they have against you, such as witnesses, photographs, videos, and other forensic evidence. Then, your attorney can make motions to suppress evidence that was obtained unlawfully and exclude the testimony of witnesses that would be more prejudicial than probative at your trial.
To get convicted, the U.S. Government will have to prove beyond a reasonable doubt that you are guilty of the offense charged. All of the 12 members of the jury must agree that you are guilty. If a reasonable doubt as to your innocence exists, you must be acquitted.
