Trump has raised millions with his mug shot. Legal experts say it could be a big mistake

Guy A Rub, a copyright law professor at Ohio State University Moritz College of Law, says that the former president could face legal consequences for using the mug shot without the express authorisation from authorities to do so.

“The copyright in the shot obviously does not belong to Trump. Generally, copyright belongs to whoever took the picture of its organisation. In this case, it is probably the sheriff’s office or the state,” Mr Rub told The Independent.

Federal law does not allow the federal government to own a copyright for booking photos, effectively leaving them to the public domain. But that is not necessarily the case at the state and local level, where using such images can be subject to fair use limitations.

“If the Sheriff’s office (or the state) wants to enforce the copyright in the image, it can probably do it,” Mr Rub added. “Copyright infringement can entail various sanctions, including the profits that the infringer, meaning the Trump campaign, gained as a result of the infringement.”
