At first, assault and battery cases might seem to be cut-and-dry. If one person physically attacks another, that individual may go to jail for the offense. However, real-life cases are rarely so simple.

After hiring a drug possession attorney to represent you, he or she will use the facts of the case and the available evidence to craft an effective defense on your behalf.
