If you look close at that picture it does look like the gun was just fired as the picture was taken so that may not have been the actual way they were standing prior.
Not defending her experience just saying this might be the equivalent of a random "O" face in a picture where the person was just have a normal conversation
My guess is it's either a staged photo or a decent time after firing, because the hammer is down, but it wasn't the instant it was fired. No smoke, no recoil reaction, etc. Either way, it'd be more than time to correct it the form…
