Thanks to PF108 for the update.
Police Beach is one of the original Lostie camps (I think, I know it's a common site for them). In this scene are Ben, Locke, Widmore, some guy named Shamus (who I have heard there named before on Island, but never paid much attention to because I didn't know who they were). Also in this scene are 4 scientist (extras).
