Several of the photos show the LEO's in clearly intentional hand postures.
That the postures appear so intentional may speak to heightened readiness, but with practice many martial practitioners appear completely natural with such gestures, and even viewed in photographic isolation, appear completely normal.
Surprising to me are the photos of such hand postures with fingers locked - very unusual for martial "ready" poses.
Or maybe we're just seeing the Secret Service (read "good guy") equivalent of "gang signs?"
Hey, just kidding!
