Somewhere For Me

I think the usual suspects were real. He could even go back and look up the arrest of them all and check for the body they buried in the sand.
But the why is most important. Why did this all happen?
The viewer has no clue
From what I understand: Keaton, Fenster, McManus, and Hockney had cross Keyser Soze without them actually knowing that they had.
Keaton was a corrupt cop and wasn't it pointed out in the movie that you could be working for Keyser Soze and not even know it?
Then again, apparently, Keaton knew who Keyser was from the first scene in the movie on the boat post killings.
I think the reason why Fenster (the one that got buried in the sand) was killed off because ol' Verbal Kint could sense that Fenster was sniffing something out not right. Fenster was the one freaking out about Keyser Soze during that scene when they met the lawyer Kobayashi.
