Also it's a bit funny how you easily shifted from being Rolecop to Alignment Cop and I can't believe people are actually willing to believe you.
Goodness gracious. How could this possibly be?! Dear me, something must clearly be wrong here!
...or not.
Let's go back and look at big picture D3, and, at least in my mind, it's pretty obvious where Krow is coming from for pretty much the whole day.
Post 1: Krow catches up on the game, having just subbed in. He finds LG/ME2,2 scummy because of the D1 Miller claim. Something a Cop would potentially find suspicious.
Post 2: gives out a list of reads
Town: Kylo/All Might, Bok, and Ayano.
Null: ME1, funnier, karu/Minish, Darth, Cheff/Yiga, TA, Libk, and Pika.
Scum: LG/ME2,2
Doesn't vote for LG at the time, despite LG being his only scum read. I will point out in this post that he actually does soft a SK-esque read on funnier. Go back and take a read on it. He uses the phrase "take a stab at it." Or something like that, anyway. Seems like a potential way to hint at funnier being the SK without him being 100% sure that funnier was the SK, which, if all he got was an Indep/neutral read, he wouldn't be.
Post 3: claims the reason he didn't vote LG was because he wasn't sure about LG being scum, and was only basing it off the Miller claim, which he was told is a regular occurrence on Bulba. He also then says that he is sure about someone else, but still doesn't vote.
Post 4: as a response to Minish, softclaims a SK check on funnier, but it's a very light softclaim. Still no vote, though in Post 5, he does vote.
By his 6th post, funnier has confirmed himself as SK, and Krow wonders who Mafia want dead more, him or the SK? Believes that Mafia was Roleblocked N2, and that Mighty Engineer were killed by SK/Vig. A good assumption based on FT.
7th post, Minish has invited funnier, who has claimed pertinent information. Krow keeps his vote on funnier.
Post 8: Krow explains his initial reluctance to put his results on funnier, which makes a lot more sense if he was the Cop and had only gotten a neutral result, and not a Rolecop with a SK result. It is now 100% confirmed funnier is SK, since funnier confirmed it, but he does ask if Town wants to keep funnier around as a second pro-Town kill or lynch him because of the possibility of randomly killing more townies.
He also reiterates that his initial read on LG/ME2,2 was solely because of the Miller claim, and was unsure.
Post 9: his response to funnier's full claim and action list, wherein funnier claimed the possiblity of a second SK in the game. Asks if funnier knows who the second SK might be.
Post 10: this is where things get a little wonky. He claims his initial post on LG was before he had received his results, and was based solely on his own judgement. That post would have either had to have been composed during N2 or posted right at the start of D3 and before Pendio gave out action results to be true. He also claims to have shifted focus from LG to funnier after receiving is results, which, even assuming a neutral cop scan, gives him a more concrete avenue to explore, given the multiple night kills strongly suggesting a serial killer's existence. Here he finally unvotes funnier and asks ME1 for a reads list, as it seems to him that ME1 knows more than he is letting on.
Post 11: explains that he'll be flying to Boston.
Post 12: comments on Libk's statement about not wanting to draw excessive attention being suspicious, and asks Libk for a reads list. (BTW, in light of Libk's flip and the results, I'd say Libk was more likely a Bomb than vengeful, since he was trying to avoid being lynched and possibly blowing up on a townie.)
Post 13: agrees with the newly subbed in All Might's plan to check Pika_Pika. Asks for a link to Darth's suspicious reads list.
Post 14: votes Darth, due to Pika's softclaim, but suggests that Pika could be bussing Darth. Pretty much confirms that he will be checking Pika during N3, in order to attempt a verification of his softclaim.
Post 15 (first post of D4): outs his results on Pika, revealing himself as the Cop for the first time.
Post 16: confirms that his result on funnier was Indep, not specifically SK.
Nothing he stated in D3 was explicitly stating he was a Rolecop, and it wasn't too much of a stretch for a regular cop to assume that an Indep result with multiple kills in the game was hostile and/or a serial killer. He obviously didn't want to fully put himself as the Cop on D3, since that would put him in peril when it was avoidable. However, since a result was expected of him as a result of D3, and he is not actually a Rolecop, he had to reveal himself to give his result.
Tl;dr: I see nothing on D3 where Krow claimed to be Rolecop, and no sign of "flip flopping" between claims.
In fact, his entire D3 mentality seems to make a lot more sense when you consider the fact that he was not 100% sure of funnier's actual role until funnier outed himself. This, of course, makes sense with funnier as a Cop and not a Rolecop.
