I'm not sure if Kero is actually a pedophile, first of all. Granted I haven't been following him as closely as the rest after we deduced that he was more of a zoosadist simp than a full-blown psycho like Snakething or Woof; he was into practicing zoophillia and necrophillia but not full-blown torture unless I missed something. Animal necrophillia and zoophillia are still horrific, for sure, but when we're dealing with people like Woof and Sephius Rivendare it's about as bargain basement animal rapist as you can get.
Secondly, after all the shit he's gone through with police scares and call-outs he is definitely not going to just take some shit idiot at their word. "I totally have videos of animal snuff and am totally not a fed," is much more questionable, and laws are being put into place to bump up the severity of crimes related to animal abuse (sexual, physical, or otherwise); so there is no longer has a statute of limitations he can crouch behind and hope for the best if he gets caught again. If he has two brain cells to scrape together he's going to be extremely cautious about who he interacts with in the future, which makes trying to Batman him a really dumb fucking idea in the long run.
And, finally, everyone already fucking knows about Kero. He's the most publicized zoophile/sadist collaborator out there, which is kind of shitty since he was probably the least interesting of the bunch. The only reason he got much track was because he was famous and people recognized him. The furry fandom just doesn't give a shit, if the videos of his buddy trolling around in his fursuit after the leaks and getting hugs and kisses for Kero is any indication. The statute of limitations on his crimes involving screwing his dog until it died of an infection and fucking the copse have long since dried up, unless he re-offends.
