probably would not have done: he transfigures a student (Draco) 
into a ferret and bounces him around, and he not only 
demonstrates all three Unforgiveable Curses on spiders but 
actually casts the Imperius Curseon his own students (I'm 
assuming all of them, at least in the fourth year and up, and not 
just Harry's class.) Either he asks and receivesDumbledore's 
permission for this blatant disregard of the laws of the WW, 
probably arguing that he's an ex-auror and that Mr. Crouch has
 authorized the aurors to use the Unforgiveable Curses, or he 
lies to the students, telling them that he has received 
Dumbledore's permission when he hasn't, a bit of information 
that would reach Dumbledore's ears rather quickly. <

Pippin:
I agree with the first part of the analysis, the real Moody wouldn't 
have bounced Draco (though as we saw with Vernon he isn't 
above a little intimidation where it will do some good). But as for 
the second, we saw in OOP that in order to learn advanced  
defensive skills, you do have to practice against real jinxes. And 
Moody confirms this, "According to the Ministry, I'm not supposed 
to show you what illegal Dark curses look like until you're in the 
sixth year. But Professor Dumbledore's got a higher opinion of 
your nerves, he reckons you can cope, and I say, the sooner you 
know what you're up against, the better." --A lie about what the 
ministry allows to be   taught in NEWT DADA (and thus tests for 
on the NEWTs) would be obvious to a lot more people than just 
Dumbledore. I think  Moody is telling the truth here.

the halls in his invisibility cloak and the fact that potion 
ingredients are missing from his office. DD knows that the 
magical eye can see under invisibility cloaks. "Moody" could see 
Harry but he let him go unpunished. Why? And he also knows, 
as Snape does, that the stolen ingredients are those used in a 
polyjuice potion.<


Pippin:
He knows something else. He knows something about what 
Harry saw and heard that night on the stairs, because Harry 
wrote it all in a letter to Sirius, and Harry, as Dumbledore informs 
him, is not Sirius's only correspondent. 

Sirius seems to have omitted telling Dumbledore about the Map, 
so probably Dumbledore doesn't realize what we (and Sirius) 
should have spotted: that it's highly suspicious that Moody said 
Crouch simply disappeared from the Map. But he does know that 
Harry spotted "Bartemius Crouch" burglarizing Snape's office.

 Dumbledore knows, as we do, that the Azkaban guards can be 
fooled and that a clever wizard can fake his own death. He would 
also remember that young Barty was a fan of Quidditch. This is 
why young Barty's trial is being studied in the Pensieve. 
Dumbledore knows what we do not find out until later :  Mr. 
Crouch's son is also named Barty Crouch. 

Carol:
Crouch!Moody shows up unasked, telling Dumbledore that 
Snape sent him. Since Snape is suspicious of Crouch!Moody 
and dislikes him, DD almost certainly suspects that this is a lie. 
Quite possibly he confirms it by talking to Snape later. 

Pippin:
I have a different take on this.  I think Spymaster!Dumbledore  
has means of knowing when there is  an intruder on the 
grounds, and also that Harry was on his doorstep.   He ordered 
Snape to call Harry back and keep him there till Dumbledore 
arrived, and then inform Moody about the intruder. Snape's eyes 
glitter  as Harry tells his tale -- a sign, IMO, that whatever Snape 
says, he *is* taking Harry seriously. 

Snape doesn't go to fetch Dumbledore because he knows 
Dumbledore is on his way, and anyway, if there is an intruder on 
the campus,  uttering the password out loud  is not a good idea. 
Since Dumbledore sent Snape to get Moody, he does not 
question  Moody's statement, so he doesn't learn that Moody 
was lying.


Dumbledore suspects that Crouch is the impostor, but he 
doesn't know *who* is being impersonated...not until Moody 
takes Harry from the scene. Snape's startled exclamation, "Barty 
Crouch!" comes because, though he also knew that Crouch was 
the impersonator, it didn't cross his mind that it could be *young* 
Crouch.
