I honestly don't put any cred at all in the whole cloning thing... I seriously doubt they can clone humans to that degree.

In this particular example, he said it himself, dude was super fat, then got super cut, skin will, naturally, shift, which would explain the slightly different tattoo positions shown, as for the "lines missing" tough to say with such a low res pic.

And for the behavior change, just look around you, people are being brainwashed left and right, no cloning needed for that...

If they could clone people this easily and readily, why would there be need for all the human trafficking at all? they could have all of the sex slaves and sacrifices for days without ever raising any suspicion, wold surely be a highly profitable market, with low risk.
