I do remember taking their reporting with a massive grain of salt as there were caveats in the story which indicated there was some sketchiness on the part of their subject and whether or not he was there or not or did the things he claimed. I took the whole thing more as a narrative with some entertainment rather than hard-hitting journalism.
