The laws about public records differ from one government to the next and are further complicated by some technologies, like police body cameras.

In 2015, the editor of a newspaper in Florida filed a public records request with the Broward County Sheriff's Office asking for the email of every employee during a five-month period to be searched for specific gay slurs.

In response, the South Florida Gay News received a $339,000 bill.

The office said fulfilling the request would take four years and require hiring a dedicated staffer. The exorbitant charge set off a year-long legal battle that attracted the Associated Press and its lofty resources. To show how arbitrary the number was, the AP and South Florida Gay News filed a similar request to the sheriff's office in other Florida counties. They were quoted fees ranging from as little as $37 to more than $44,000.

Why then is there such a big range of costs for similar information?
