Narrative:
We were flying an ILS 10 syr as air carrier flight xyz. Visibility was reported as 1 mi. Inside the final approach point, we estimate at about 1400 ft AGL, a high wing small aircraft sel flew directly beneath us perpendicular to our course, heading south. The WX was no where near as good as the tower was reporting. There was no way the small aircraft was 1 mi or clear of clouds. After landing we called the tower and spoke with the tower supervisor. He was very apologetic and explained that the small aircraft sel was a traffic reporter for a local station and that he had been instructed to stay north of the localizer, but had turned south against those issued instructions. The aircraft was very clearly operating in solid to broken IFR conditions, and also operating contrary to his ATC clearance. We did not see the aircraft until he was coming under our aircraft from the left due to the poor WX. If our aircraft had been TCASII equipped we would, I'm sure, have executed a TCASII avoidance maneuver.

Title: NMAC BTWN AN ACR MLG AND AN SMA SEL TFC WATCH ACFT DURING FINAL APCH IN IMC.
Narrative: WE WERE FLYING AN ILS 10 SYR AS ACR FLT XYZ. VISIBILITY WAS RPTED AS 1 MI. INSIDE THE FINAL APCH POINT, WE ESTIMATE AT ABOUT 1400 FT AGL, A HIGH WING SMA SEL FLEW DIRECTLY BENEATH US PERPENDICULAR TO OUR COURSE, HDG S. THE WX WAS NO WHERE NEAR AS GOOD AS THE TWR WAS RPTING. THERE WAS NO WAY THE SMA WAS 1 MI OR CLR OF CLOUDS. AFTER LNDG WE CALLED THE TWR AND SPOKE WITH THE TWR SUPVR. HE WAS VERY APOLOGETIC AND EXPLAINED THAT THE SMA SEL WAS A TFC RPTR FOR A LCL STATION AND THAT HE HAD BEEN INSTRUCTED TO STAY N OF THE LOC, BUT HAD TURNED S AGAINST THOSE ISSUED INSTRUCTIONS. THE ACFT WAS VERY CLRLY OPERATING IN SOLID TO BROKEN IFR CONDITIONS, AND ALSO OPERATING CONTRARY TO HIS ATC CLRNC. WE DID NOT SEE THE ACFT UNTIL HE WAS COMING UNDER OUR ACFT FROM THE L DUE TO THE POOR WX. IF OUR ACFT HAD BEEN TCASII EQUIPPED WE WOULD, I'M SURE, HAVE EXECUTED A TCASII AVOIDANCE MANEUVER.
