You see, the level of "CYA shenanigans" is directly proportional to the amount of Monday-morning quarterbacking that we see in the aftermath of any event like this.
That sounds neat in print but it doesn't really work that way. Having neatly avoided becoming the sacrificial goat myself on the final phase of a 100 million dollar Superfund Job I can tell you that a good CYA is a sight to behold. In theory it allows ones immediate superior or higher to:
a) take credit for good stuff you do and;
b) make it look like you were responsible for the bad.
Keeping really good notes and records, even if you have to keep said superiors from seeing or knowing of them, is a must to fend it off.
The masses Monday morning QB'ing is irrelevant.
We'll see how this unfolds...
