I thought that the military training camp had tighter security but today quite a few pictures of Jin engaged in duties on the base have made their way to Sites. He is not aware the pictures are being taken as some are at a distance and from the side. A few are close, possibly thru a telephoto lens.
I am sure other idols have had their pictures taken during basic training as well. Is it fellow soldiers or an unsecure area or maybe civilians snapping pictures visiting the base?
