If they had concerns about missing anything important (or at least anything that might prevent them doing their job) they would have said so.
they were "severely restricted" in their access to the evidences ...
How they can know they have missed anything important .. as they were "severely restricted" to acces of evidence ?
How you can know about something visual is important or not .. when you can't seen it yourself ?
Why they can see only photos (courtesy of BEA .... ) .. but not the real thing ?
Experts working (investigate) on photos .. when all material is available somewhere to be examined
Forensic working with photos of a deadman cause restricted to touch the body in the morgue ?
Weird isn't it ?
