Kogoro's knowledge about the situation

[Shuusgirl]

I think he knows at least something. In the White Day case.. (I think that's out in anime quite soon but I'll use spoiler boxes as ftsh hasn't read the manga yet).

Spoiler:

Anyway, in the White Day case Kogoro knows that there's always a sort of prick feeling usually in the back of his neck or forehead after he hears his voice from somewhere. This seems to point towards him suspecting something is up with the Sleeping Kogoro stuff but not (at that time) suspecting Conan

Also, during the Red Shirts case, I reckon that he could hear his voice but didn't know who was talking using his voice (which fits in with what I said about the White Day case), after all he possibly just planned to keep his eyes shut until the deduction finished. This bit is just my opinion though.
Also, about file 766:

Spoiler:

I think that part of Kogoro not saying that Conan was disrupting the scene had to do with Conan freaking out about the evidence being destroyed after they tried to move the body. Although, recently Conan has been acting more Shinichish so that might also add to it.

Totally agree.  Lately Kogoro's been treating Conan like...well, maybe not an equal, but he hasn't treated him as a little kid like he normally does.  I don't think he knows that Conan=Shinichi (really, who would jump to that conclusion?) but Conan does say that Shinichi tells him stuff, so that would explain why he acts like Shinichi.

[ftsh]

If Kogorou knew about Conan doing the detective work, the chance of him seeing Conan as Shinichi is still low.
Even though the watch with tranquilizer is weird enough, he wouldn't reach the point of believing that Shinichi shrank that easily.
In the earlier episodes, again assuming he knew that Conan was the real Sleeping Kogorou, he probably saw Conan as a brilliant detective and nothing more, possibly using him as, much like in his case, most people won't believe what a kid says.

Notice that similar to Ran, Kogorou witnessed Kudou's appearance when Ai disguised as Conan was around in the desperate revival arc. A contradiction appears, so he would probably think of possibilities whether or not Conan is Kudou but in all probabilities he probably sees Conan similar to Ran right now, just an exceptionally intelligent boy. (who allegedly learns everything from TV, not exactly a good message to convey to public. lol) By not exposing Conan as being the real Sleeping Kogorou, he gets to continue enjoying his fame and the likes while nothing harmful is going on. (at least in his case. he probably didn't know much about BO nearly killing him.) Thus to him it would be better if he kept quiet anyway. And let me repeat this again, I'm fairly indifferent to this theory, but all the things here are assuming he knows. Although of course, if he didn't feel anything wrong since Conan's appearance then it'd be ridiculous.

(thx stopwatch for the spoiler tags)
First for the late paragraph, it wouldn't be that hard to figure that someone was disguised has Conan or Shinishi (since in the series is so easy for someone to look like someone else, examples: shinishi = Heiji + Tan).

Then again if I had full evidence Kogorou knew Conan's identity this wouldn't be a theory would it? I'm quite suspisous he knows, and as my way of seeing the things explains the facts, yours also does. And until further development it would be quite hard to know who is right.

[Crap4869]

So the fact that Kogorou began respecting Conan as someone capable enough in detection instead of just a kid is now more or less established. Now we're left with the question: does Kogorou know Conan's true identity? I'd say probably not yet. With all the TV, 'learning from Kudou' and other excuses, that might or might not mean anything in this (specifically Kogorou's) 'problem.'

To add on, another possible reason why Kogorou didn't expose Conan is that he needed more information. So this makes sense if Kogorou didn't know Conan is Kudou, he needed to continue playing dumb so he can collect as much data as he wants about Conan without Conan knowing. (since Conan would assume Kogorou's asleep as usual.) If Kogorou ever finds out Conan = Kudou and reveals it then we can safely say DC is probably ending soon :V so we have to wait for quite some time for this. lol

I don't know whether anyone mentioned all these before lol but anyway I'll stop here until I think of more possibilities.

And oh, ftsh = future time sherlock holmes? lol. just a random guess.

Nope but it is has dumb has that.

Thank you for doing what I though to do, I will go as far to say that it can be established that kogorou knows that Conan is solving the cases and work under that assumption.

I'll put myself in the character and make a train of though

(assuming that he discovered that in the first 100 cases:)

So... ok that kid sends me to sleep and solved the cases.

But, how?

For this question and overruling magic and knowing that he doesn't always dress the same, it has to be something that the kid always carries, so his wristwatch,  his necktie and his glasses need to do the trick, through machineries of course.

How did he get his hands on that?

(obvious response knowing his relation with Agasa) Agasa, of course!
But a taser is something that you wouldn't give a kid, not even for playing and even if it was some kind of sick joke he would've already told me,  so he must have a lot of trust in him. That's quite strange judging by Conan's age.
------------------------------------------------------------------------------------------------------------

From there Kogorou could do a background check in Agasa's friends and start forming the link Conan-Shinishi, link that could deepen with the time (again I seriously lack proofs for this part, so it is pretty hard to impuse my opinion)

In the same note, I agree with you, once Kogorou reveals that he knows Conan's identity the show is pretty much reaching its ending, so I don't expect it to happen so soon....  (of course we could have an Shinishi saga after that, so it isn't necessarily the end of DC)

[Kogorou]

I think somewhere Kogorou knows what's happening but it's for his benefit so why should he try to stop it. Ever since Conan showed up his reputation raised extremly and it all works out. As long as he doesn't see a reason he will not take any action. Someday he will have to because I think that Kogorou will have bit part in the solution. He's way to selfish to let it slide. Someday we will see the true face of Mouri Kogorou and his capabilities. Oh how I long for that day to come.

And do you really think that he will even tell anyone? No, even if he could make the link to Agasa he wouldn't tell. For Conans safety. He likes Conan even if he doesn't show it.

In answer to your retoric question, I don't think, in fact I completely agree with you, as my way of thinking of his character his probably the same as yours.

[Kogorou]

You are right

I gave that stuff much thought. Kogorou was a Policeman and after he left the force he became some kind of slacky because Eri wasn't around. Given the fact that Eri was the reason for leaving after beeing used as an hostage things chanced.
If I were in his position I wouldn't tell. Even if I would find out that Conan is Shinichi (okay I would make a fuss and talk to Conan about "things" just take the bathing together and stuff) I would try to help him.

[Tanner-kun]

ftsh = Fetish

^I also thought that.

Is it fish?

[ftsh]

ftsh = Fetish

^I also thought that.

Is it fish?

Nope and it isn't fish is ftsh , (although I found the typo quite funny)

(more in-theory later)

[ssjup81]

To be honest, I'm surprised no one else has gotten suspicious enough to figure out something wasn't quite right since Conan appeared, aside from probably

Spoiler:

Eisuke.  It's fun how he deduced that Conan was Shinichi and put two and two together.  Shinichi vanishes, this kid shows up, and miraculously, Kogoro starts making good deductions.

 

[Kogorou]

Now it totally seems that Kogorou seems to know something but we can't tell all we have is a suspicion that we can't proof.
Maybe there will be something.
I noticed that Kogorou helps Conan out and let him run around more freely. Maybe we can make something out of that.

@ssjup81
Yeah he was great maybe he will be back.

[Stopwatch]

@ssjup81
Well, actually I reckon that it's more that they've got used to him (Megure), they think it's normal (Detective Boys) or they just don't want to ask ((Takagi) if only..). I'm not sure it's been mentioned before but in the really early episodes when Conan wasn't sure how to act 'childish' he let a lot slip. Middle eps he acted a lot less suspiciously and in the later ones he's been acting more like Shinichi again. This is probably 'cause people actually listen to 'Conan' now so he forgets to tone down stuff and no-one bothers to stop him, also (as in the case of Yamato, (sorta)Eri, (sorta)Sato and Kid) they see straight through the attempts at childishness so he just doesn't act like a child around them. The fact that there are now even more people who know who he really is and it becomes clear that Conan should be very, very glad that none of the suspects in cases have pointed it out and forced everyone else to face what they've been carefully avoiding. Essentially, I think that for more than half the cast Conan's 'weirdness' is the elephant in the room. 
Another factor is that he shields (right word?) himself more among certain people, an example would be to compare the Detective Boys and Ran. With Ran he probably acts the least like Shinichi, primarily 'cause she'd be the most likely to realise the similarities (something that's happened almost every time he does something remotely like Shinichi) but with the Detective Boys he's almost himself to the point that whenever he acts immature in front of adults they're just there wondering why? with annoyed looks and tell him off for it (like in that ep with Kobayashi when Haibara kept telling him to slow down so he wouldn't seem suspicious and Genta and Haibara imitated his 'al-le-le',  loved that one). 
And even more off topic here but can I just say that I may have gone a bit overboard with the brackets so sorry 'bout that.
Anyway, what I'm trying (and probably failing) to get across is that if there's any time people are gonna figure it out and either confront Conan or keep it to themselves, it is now.
And on that bombshell, good night... (Why am I quoting Top Gear?!  )

[Shuusgirl]

Remind me, did Eisuke know that Conan was Shinichi immediately, or did he suspect until he got "proof"?  'Cause in the first few episodes with him around, he asked a lot of questions, especially about Conan and his position near "Sleeping Kogoro".

[Abs.]

He claims to have already known from the start, hence him greeting Conan as "Mouri tantei" upon their first meeting.

[Kleene Onigiri]

Tho he trapped Conan into admitting it with saying that he would steal Ran So in the end, he didn't say it out loud either.
I think that is also a factor for Ran and Mouri. Even if the think that Conan is Shinichi, saying it out loud would be strange for them. They fear to be wrong and people would think they are insane.
Even in the times Ran thought Conan is Shinichi for sure, she never mentioned it to anyone, not Sonoko or Kazuha etc.

Also, in Kogoros case, I would think I'm a Shizo or a psychopath or ill or something if I don't suspect Conan/being darted all the time. Since he looses consciousness all the time
