Our Clarksville federal criminal defense attorneys can investigate your case, collect evidence, review evidence gathered by federal agents, and develop a strong and tailored defense strategy to help you avoid serious criminal penalties or even get your case dismissed altogether.

The Difference Between Federal & State Crimes

Most crimes in Tennessee violate state law, which state lawmakers have enacted to address state-related concerns. On the other hand, federal crimes involve matters of federal or national interest, such as drug trafficking, weapons and explosives charges, mail and wire fraud, tax evasion, terrorism, and immigration crimes.

The federal court handles the following types of criminal cases:

  • Crimes committed on federal land – Common examples include robbery of a federal bank, destruction of property in a national forest, and homicide on a military base.
  • Crimes committed throughout multiple states – For instance, identity theft involving many victims in different states.
  • Crimes when an offender crosses state lines – For example, transporting drugs from one state to another.
  • Violations of immigration and customs law – Common examples include international sex trafficking or distributing child pornography.

Federal crimes are punishable by longer sentences compared to state crimes and can include time spent in federal prison. Some charges, such as drug crimes, are associated with mandatory minimum sentences.

Our Clarksville federal crime lawyers can thoroughly assess your case, figure out all your available legal options, and help you obtain the most favorable result in federal court. We understand the complexities of the criminal justice system and we will take aggressive legal action in your favor.

  • “Jeff Grimes is an absolute rockstar!”
    Jeff Grimes is an absolute rockstar! I’ve had some not-so-great experiences with lawyers in the past, but when I found myself in trouble, Jeff was the first person I called. From the very first phone call, he was super open, honest, and set realistic expectations. I was already feeling good about hiring him, but at my arraignment, he did more for me than most lawyers do throughout the entire case. That’s when I knew I made the right decision. Edina (she was amazing and I’m so grateful for her honesty and calmness which helped with my nerves) and Jeff, along with everyone else I’ve worked with, have made me so happy I trusted them. For me it's not only about the resolution (I plead out) but the honesty and openness, so if you prefer that too then Jeff is your guy.

  • “Best defense lawyer you could ask for.”

    Grimes is the best defense lawyer you could ask for. He was able to take what would generally be a felony for sure and get it down to a misdemeanor and a fine. If you have him as your lawyer, you won't have anything to worry about.
