Read Ledwith's own detailed account of his visit to the house on the 22nd (D & B report, pp. 42 ff.). He interviewed both the women and the men collectively (in the case of the men, with one or another coming / going during the process) and progressively refined his sketches in response to their collective feedback.
There are, unfortunately, two key moments when impartiality is arguably comprised.
Having completed his first sketch, as depicted by the women (minus Mrs Taylor, who had not seen the small creatures), Ledwith explains:
WE RETURNED TO THE HOUSE, AND ABOUT 1:45 BILLY RAY TAYLOR WALKED IN, GUN IN HAND, RETURNED FROM HIS HUNTING TRIP. I QUIETLY LAID THE WOMEN'S DRAWING ON THE BED NEXT TO WHICH I WAS STANDING, AND MOVED AWAY. BILLY RAY CAME INTO THE ROOM, GLANCED AT THE BED, SAW THE DRAWING, RAN OVER AND PICKED IT UP, AND GAVE US ALL THE COLD CHILLS BY DECLARING, "THAT'S IT,BTHAT'S IT, THAT LOOKS JUST LIKE IT!" I THEN ASKED HIM INTO THE OTHER ROOM (THE BEDROOM) AND WE STARTED TO DRAW A SECOND PICTURE, USING THE FIRST AS A BASIS.
(End)
So, Billy Ray already knows what the women believe is accurate.
Then later, as Ledwith records:
THIS WAS THE SCENE AND TEMPER OF THE PEOPLE WHEN LUCKY DESCENDED AT 3:30. ...JUST BEFORE HIS ARRIVAL WE HAD GONE INTO THE BEDROOM, WHERE BILLY RAY TAYLOR WAS TALKING TO HODSON. THE DOOR WAS THROWN OPEN, AND IN STRODE LUCKY, SCOWLING. "WHAT’S GOING ON HERE?" I FELT THAT HIS MOTHER HAD MET WITH HIM IN THE FRONT YARD AND HAD BEGGED HIM TO REMOVE ALL SIGHTSEERS FROM THE HOUSE AND SURROUNDINGS, AND HE WAS ABOUT TO START WITH US. HOWEVER, BEFORE HE DID ANYTHING ELSE, HIS EYES DROPPED TO THE TABLE WHERE THE WOMEN'S DRAWING LAY. WITHOUT SAYING ANOTHER WORD, HE SAT DOWN, AND WE KNEW WE HAD STRUCK HOME WITH THAT PICTURE. HE LOOKED IT OVER, STARTED TO SHAKE HIS HEAD, AND SAID, "NO, THE FACE IS ALMOST ROUND, IT DOESN'T COME TO A POINT." THE OTHER TWO MEN HAD NOW COME INTO THE BEDROOM, TOO, AND WE GOT RIGHT TO WORK ON THEIR DRAWING, USING THE WOMEN'S AS A GUIDE AND MAKING CHANGES AS THE MEN INDICATED.
(End)
Once more, the men are presented with a fait accompli.
Although in both cases changes were made to the sketches which had been seen, in neither were sketches compiled from scratch, based on the witness descriptions.
When Taylor is given an opportunity to effectively start from the beginning and Pt. Hodson's artist draws a separate sketch based on this, Ledwith puts the variance between his drawing and the other as Taylor 'elaborating'.
How could he be sure the other sketch wasn't in fact more reliable?
Would it be reasonable to conclude that given the lighting conditions, perhaps none of them are.
