US police are well-known for releasing photos of recent arrests, a policy that has given the world some iconic photos of celebrities who have fallen foul of the law.
In a recent case in Tulsa, Oklahoma, the release of alleged sex offender Stephen Olsen's mugshot has prompted widespread hilarity, due to the unfortunate juxtaposition of Olsen's expression with the vile crime he is accused of.
Olsen was arrested and charged with indecent exposure after police fielded numerous complaints that he had pulled his pants down and touched himself in a sexual manner in the middle of a public park.
Police announced the arrest in a news release with the subject line: "Chronic Masturbator Caught."
