[1][2] The primary purpose of the mug shot is to allow law enforcement to have a photographic record of an arrested individual to allow for identification by victims, the public and investigators.
However, in the United States, entrepreneurs have recently begun to monetize these public records via the mug shot publishing industry.
Photographing of criminals began in the 1840s only a few years after the invention of photography, but it was not until 1888 that French police officer Alphonse Bertillon standardized the process.
In 1888, Alphonse Bertillon invented the modern mug shot featuring full face and profile views, standardizing the lighting and angles.
[11] The arrested person is sometimes required to hold a placard with name, date of birth, booking ID, weight, and other relevant information on it.
[citation needed] In some jurisdictions, mug shots are not legally required to be taken, mostly in the cases of high-profile individuals already known to a wider public.
The United States Court of Appeals for the District of Columbia Circuit held, "The double-shot picture, with front and profile shots alongside each other, is so familiar, from 'wanted' posters in the post office, motion pictures and television, that the inference that the person involved has a criminal record, or has at least been in trouble with the police, is natural, perhaps automatic.
