Nope, I didn't read it wrong luv .... why should I be held accountable for an ID THAT I PERSONALLY NEVER SAW? What guarantee do I have that the "original" producer hasn't changed the "original" document in some way? Zip, Zero, None.
How does my having a "copy" of said document make the guy any more or less legal than he was when the material was produced and said documentation viewed by the one actually taking the photos/video? The one(s) responsible for age documentation should rest squarely on the shoulders of the person, or the company that hired a person, to photograph the model. Period.
