Knowing Ohio laws pertaining to gun sales and purchases, as well as those issued at the federal level, is always a good idea. However, simply possessing such information may not be enough to help you avoid legal trouble related to firearms sales. If you are charged with a crime involving the private selling of a gun, you can protect your rights in the following ways: By fighting the charges against you By understanding that anything you say or do during an investigation or throughout the process of arrest can later be used to incriminate you in court By retaining immediate assistance from a skilled defense attorney By allowing your attorney to challenge evidence against you if it is determined that your rights were violated when said evidence was gathered
