Narrative:
Bwi approach was down to center radar (their own was out of service) initial turn on to localizer was normal. Descending through 3500' the first officer excitedly reported 'traffic straight ahead.' it was an small aircraft at 3000' flying directly through the localizer for bwi. We didn't have to pull up much but simply stopped the descent. As a matter of procedure we reported the incident to approach. The controller was concerned, but not about our near-miss. He explained that he was down to primary radar only. We said that 'we are not pointing fingers we just wanted you to know.' pilots and controllers are so concerned about FAA violations that we make mistakes from constantly looking over our shoulders. Whose fault is that? No one except the FAA. Where is our kinder gentler administration?

Title: FLT CREW OF MLG ARRIVING BWI HAD NEAR MISS WITH ANOTHER ACFT FLYING THROUGH THE LOCALIZER.
Narrative: BWI APCH WAS DOWN TO CTR RADAR (THEIR OWN WAS OUT OF SVC) INITIAL TURN ON TO LOC WAS NORMAL. DSNDING THROUGH 3500' THE F/O EXCITEDLY RPTED 'TFC STRAIGHT AHEAD.' IT WAS AN SMA AT 3000' FLYING DIRECTLY THROUGH THE LOC FOR BWI. WE DIDN'T HAVE TO PULL UP MUCH BUT SIMPLY STOPPED THE DSNT. AS A MATTER OF PROC WE RPTED THE INCIDENT TO APCH. THE CTLR WAS CONCERNED, BUT NOT ABOUT OUR NEAR-MISS. HE EXPLAINED THAT HE WAS DOWN TO PRIMARY RADAR ONLY. WE SAID THAT 'WE ARE NOT POINTING FINGERS WE JUST WANTED YOU TO KNOW.' PLTS AND CTLRS ARE SO CONCERNED ABOUT FAA VIOLATIONS THAT WE MAKE MISTAKES FROM CONSTANTLY LOOKING OVER OUR SHOULDERS. WHOSE FAULT IS THAT? NO ONE EXCEPT THE FAA. WHERE IS OUR KINDER GENTLER ADMINISTRATION?
