Daniel Rosen, a senior State Department official arrested last month for soliciting sex online with a minor, was reportedly arrested again Sunday night in Washington, D.C., and charged with an earlier crime of voyeurism after police searched his cellphone. And he is only the latest in a long string of government employees to have been accused of crimes against children.

Public records and reports reviewed by The Daily Beast show that at least 22 current and former local, state, and federal employees have been convicted of crimes ranging from distributing child pornography to conscience-shocking acts of violence against infants. The crimes have occurred over the past decade, with many of the cases coming in the past four years. Experts say the numbers are likely far higher and may not be thoroughly documented by law enforcement agencies across the United States.
