Can you tell me the meaning of this sentence?

THIS CONVERSATION FROM MONK








MONK : Here's what happened


I mean, here's what really happened.





When Keyes started playing drums


a few weeks ago,





he wanted the neighbors to complain.


That was the key to the whole plan.





Last night, the machine TOGO


must have been on a timer.





It kicked on at 10:30 while Keyes was


across town robbing the jewelry store.








Officer. It's Marge Johnson.


He's doing it again.





Marge didn't see anybody


drumming last night.





What she saw was a machine.TOGO





MR KEYES : Very clever, Mr. Monk


I'll take that gun, captain.


CAPTAIN: Hey, Keyes, you don't want to do this.


You don't want to kill a cop.


MO NK- Or a ex-cop.


NATALIE- Or a ex-cop's assistant.


KEYES: You, blondie


Gimme your car keys.


Come on! You're not gonna need'em.


All right. Down on your knees.


Do it!


Captain, get down!


RANDY : Togo! Down, now! Now! Now! Move!


Togo, drop it!


Togo, no!


I knew it.<br>


I knew it. He's sentient. He's alive!


<You guys okay? Science fiction,


>


CAPTAIN: Yeah, ah...


<They were in it togetherHim and the, robot.


RANDY: Well, that explains almost nothing.


CAPTAIN:<You did what you had to do, lieutenant.








I WANT TO KNOW" Well, that explains almost nothing" MEANS



It means that he does not get it. He did not follow what they were talking about. He is still confused, and what they said didn't help him understand anything. It means that they confused him even more.
