Narrative:

This was a typical ind-rsw flight. No problems while on radar vector in a descent that would put us on a long left-hand base to runway 06. We had to take evasive action to miss an small aircraft at approximately 5500' while descending into a broken deck of clouds (approximately 6000-4000'). Unannounced traffic appeared at 12 O'clock and less than 1 mi, climbing up our descent path. In my best estimation, we were on a collision course. I immediately, west/O hesitating, instinctively pushed the aircraft down and to the right to avoid impact. The captain was engaged in a conversation with the acm on the jump seat. He immediately turned to look at me, then saw the small aircraft pass by his left window at approximately 300' level. We all sat in quiet for the next few mins, not being able to speak. The acm said he did not see the aircraft at all. It was over before it began. Approach control called the traffic at 12 O'clock and at our altitude after it had just passed. They called it 1 mi--it was by then 1 mi behind us. The F/a's wanted to know what had happened. The captain refused to tell them. I asked if he wanted to report a near miss to ATC. He said 'no, too much paperwork.' my conscience will not allow this to go unrpted. Fmy is an accident waiting to happen.

Narrative: THIS WAS A TYPICAL IND-RSW FLT. NO PROBS WHILE ON RADAR VECTOR IN A DSNT THAT WOULD PUT US ON A LONG LEFT-HAND BASE TO RWY 06. WE HAD TO TAKE EVASIVE ACTION TO MISS AN SMA AT APPROX 5500' WHILE DSNDING INTO A BROKEN DECK OF CLOUDS (APPROX 6000-4000'). UNANNOUNCED TFC APPEARED AT 12 O'CLOCK AND LESS THAN 1 MI, CLBING UP OUR DSNT PATH. IN MY BEST ESTIMATION, WE WERE ON A COLLISION COURSE. I IMMEDIATELY, W/O HESITATING, INSTINCTIVELY PUSHED THE ACFT DOWN AND TO THE RIGHT TO AVOID IMPACT. THE CAPT WAS ENGAGED IN A CONVERSATION WITH THE ACM ON THE JUMP SEAT. HE IMMEDIATELY TURNED TO LOOK AT ME, THEN SAW THE SMA PASS BY HIS LEFT WINDOW AT APPROX 300' LEVEL. WE ALL SAT IN QUIET FOR THE NEXT FEW MINS, NOT BEING ABLE TO SPEAK. THE ACM SAID HE DID NOT SEE THE ACFT AT ALL. IT WAS OVER BEFORE IT BEGAN. APCH CTL CALLED THE TFC AT 12 O'CLOCK AND AT OUR ALT AFTER IT HAD JUST PASSED. THEY CALLED IT 1 MI--IT WAS BY THEN 1 MI BEHIND US. THE F/A'S WANTED TO KNOW WHAT HAD HAPPENED. THE CAPT REFUSED TO TELL THEM. I ASKED IF HE WANTED TO RPT A NEAR MISS TO ATC. HE SAID 'NO, TOO MUCH PAPERWORK.' MY CONSCIENCE WILL NOT ALLOW THIS TO GO UNRPTED. FMY IS AN ACCIDENT WAITING TO HAPPEN.
