In some cases, the difference between facing state-level charges or federal charges is simply where a crime occurred. This is very important when looking at certain crimes that may cross state lines. This can trigger federal charges because the federal government has jurisdiction if more than one state is involved.
One example could be transporting illegal drugs. If you were found with illegal drugs in your possession in Michigan, you could face serious state-level drug charges. But if you were found driving across state lines, such as bringing those substances from Michigan into Indiana, then you could find yourself facing federal charges.
The specifics of the crime—the type of substance in question, the total amount that you had at the time of the arrest and other details—may be identical, but the fact that you crossed state lines during the commission of the crime significantly changes how your case will proceed and the ramifications you may face.
Internet-based crimes
Another area where this can apply is if alleged criminal activity takes place on the Internet. An example could be online financial fraud.
If you are accused of fraud, you may have been in Michigan the entire time. But if you have defrauded people all across the United States, then you could find yourself facing federal charges. The criminal activity still crossed state lines, even though it was digital in nature.
Your defense options
As you can see, these types of federal cases can get fairly complex. It is very important to understand the exact charges you are facing and what legal defense options you have as your case moves forward.
