An aggressive defense attorney will interview the client in their office or at the jail. The interview will revolve around all relevant witnesses personally or through an investigator. The lawyer will examine the crime scene, obtain the necessary court orders to obtain evidence, subpoena evidence and documents, file motions for discovery, analyze the case through legal research, write and litigate all relevant pre-trial motions, such as motions to suppress evidence or statements based on violations of constitutional rights, prepare and try cases before judges and juries and present arguments at sentencing in mitigation on behalf of his clients.
