If Fluttershy lives in Ponyville you must acquit.

@The Twelfth Doctor Whoof  
The Chewbacca Defense could be destroyed by anyone that pays attention the Star Wars, Chewy was only on Endor for what we saw in the movie, the defense says he lives there, nothing even suggest he does.

Sorry, Ghost of Johnnie Cochran, but it actually makes perfect sense.
 
Fluttershy lives in Ponyville because everypony in Cloudsdale treated her like shit, so when she fell to the ground, she decided to stay there. Also animals.
 
Now YOU, on the other hand… Johnnie Cochran is a defense attorney famous for getting O.J. Simpson off for murder using the Chewbacca Defense*, but Johnnie Cochran died years ago and wouldn’t know anything about My Little Pony. That does not make sense.
 
_{*The Chewbacca Defense was just some stupid bullshit South Park made up, but Cochran did bamboozle the jury.}

Was it part of the joke that Chewbacca ISN’T from Endor?

The chewbacca defense won’t work with this.

It makes sense.  
Somehow…

Well from what we’ve seen, she isn’t much of a flyer and animals are on the ground. So yeah, it does.

there are no animals in cloudsdale so it DOES make sense

Other pegasus live there too, so it does make sense.
