Does Maryland need a special prosecutor to investigate the state prosecutor’s office?

Last week State Prosecutor Robert Rohrbaugh had his office send out a new round of subpoenas in his investigation of Baltimore Mayor Sheila Dixon. According to news reports, Rohrbaugh issued the subpoenas to find out more about four development projects. Ronald H. Lipscomb, a Baltimore developer who was one time linked to Dixon romantically and exchanged gifts with her, is said to be involved in at least three of those projects.
