Nah mate, this recovery has been pretty abysmal thus far. Look at the photos of the tail section recovery. They won't know what scrape, scratch, break or tear resulted from the crash and which one from the recovery. No post mortems on the bodies recovered thus far...
No professional investigator or materials engineer would be confused by scrapes or scratches from the recovery effort.
And post-mortems are performed for each and every body recovered so far. This was already
explained before.
It's worth to re-quote bud leon:
"If you are just going to take barely-informed pot shots from the sidelines, it says more about you than it does about them."
