The Child Protection Agency was created as the authoritative branch of the state to steward and defend society's most valuable natural resource. The CPA employs a variety of officers specializing in investigation, enforcement, technology, forensics and support. As well as its own special field agents who specialize in investigative/enforcement, the department also has direct access to its own detachments of enforcers.
Though the CPA building is large and imposing, appearing to be designed for large amounts of workers. The department would appear to be largely underused and vacant. This is likely largely due to the population implosion which afflicts the whole of society.
