So Richard's people are on Ben's team? There really was no good explanation for all this, and why were they still wearing makeup when they ambushed kate and sayid? No one on this island really believes in "the others," as in native inhabitants dressed in rags. SO why are these people still doing it? Is it possible that they aren't dressing up, and that they are the true hostiles (not affiliated to Ben)?

Camo gear!

I assume they look like they've been living in the woods for an entire season because... they've been living in the woods for an entire season.
