Ran into something similar a couple weeks ago...

Hunter: "Have you see any animal? We have a 22"
caddisguy: "Not really, just the grouse we got yesterday"
Hunter: "What's a grouse?"
caddisguy: "A tasty bird"
Hunter: "Oh you so lucky"

After this exchange I wondered

a) How someone could have passed their CORE and not know what a grouse is
b) What they planned on shooting in this valley with a 22 other than grouse (no opening for snowshoe hare)

Anyway, it is definitely irritating how in the article they kept calling these violations "mistakes" ?

Taking the gull bladder... oh just a mistake, nothing to see here
Leaving the meat behind... ooh just a mistake... nothing to see
"Forgetting" where the carcass was left.. oops, just a mistake, no big deal
Misidentifying a cow as a bull moose... thought it was cows with antlers, not bulls... another honest mistake
Forgets where another bear carcass was left.. oops... turns out to be a grizz... oops
"Mistakes" muley for whitetail... just another "mistake"

Anyone who even entertains the idea that any of these were "mistakes" or anything other than blatant disregard for the law and hoping not to get caught is gullible.
