Now investigators can't have the false assumption that when they take down one site that the attack is done.

It is an arms race, another tool in the arsenal.

Just as a home owner has a gate, a lock on the door, an alarm and a safe, so banks need to have multiple layers of security.

You proceed from a false assumption: I have no ego to bruise.

We don't know the answer to that question. That's one of the things investigators are looking into, but it would be unwise for us to speculate on that at this time.

There's the assumption, when getting tissue, that it has been inspected and that it is safe.
