Having A Former Prosecutor On Your Side Can Make A Difference

Before establishing his own practice, John R. Kopp worked as a prosecutor for the Cook County State’s Attorney’s Office, where he handled numerous criminal issues ranging from traffic offenses to first-degree murder.

Many of his cases involved preparing police officers for their testimony at trial. Through that process in hundreds of trials, Mr. Kopp gained a thorough grasp of police investigations, warrant executions and arrest procedures. He can use that knowledge to effectively evaluate how the prosecution will approach your case and develop a strong defense for you.

Mr. Kopp knows courtroom procedure. He’s built relationships with prosecutors to understand their approach to their cases. And he knows criminal law. Don’t trust your case to a less-experienced lawyer.
