I believe those pictures were posted here some time ago. Why snopes has pictures of wels in a story about noodling, or hand fishing for Ictalurids, beats me.
There was actually a NY Times article on noodling a while back. I think it's more for the thrills than the fish
Beleive it or not they have made noodling illegal in some states along the mississippi river basin. Cant recall but i think missouri is one. Dont know why its illegal its probibally easier on the fish than hook and line fishing. Personally I think Id pass on wrestling flatheads underwater.
Noodling is illegal because it is: a. considered dangerous and more importantly, b. it depletes natural stocks of catfish faster than hook-and-line fishing. The main target of noodlers are nesting catfishes. Once the guarding parent is captured, this exposes the eggs/fry to predation.
