Narrative:

A cessna was on sfra (special flight rules area) frequency at pct on a surveillance mission. He strayed into class delta from the north without communication with the tower heading in a wide turn. I issued the altimeter and traffic including the altitude of the other aircraft but may have said 'ahead and to the right' when the traffic was more correctly ahead and to the left. After making another transmission while working the position; I went back to call traffic again saying; 'traffic; cessna; straight ahead 1/2 mile at 800 feet.' moments later aircraft saw the traffic but saw him passing below and said; 'that was close.' this should have been a traffic alert call. The pilot declined to file any paperwork on the incident. This was a busy session on position but either the tower; myself; or the controller working the sfra west position should have provided better service to the surveillance aircraft taking in the complexity of his mission while he was actively trying to coordinate the sfra; and the tower and fly his plane while operating. I think the current policy in the 7110.65 that the sfra controller doesn't have any airspace and doesn't have to call traffic is potentially dangerous.
