Odd, I haven't seen it. As a matter of fact, I've never even heard of any pictures/video of someone detained inside a crime scene, making it out to the public.And that could be anyone, including witnesses, victims, and first responders. Hopefully not, but it happens a lot.
All pictures I've seen have been outside the scene...as all the witnesses/victims of a shooting incident usually hurry outside unless they are detained by the responding officers
