I think the idea behind no-blame culture is that a single person shouldn't be able to cause a massive incident on their own (assuming no malice), so finding a victim to put the blame on isn't helpful anyway. Also, if you start blaming people, everyone will go in permanent cover-my-ass-mode and this will usually just lead to some poor junior, who couldn't play the game yet, getting the full blow. Of course, letting people run rampant and acting everything is fine is not great, but there's a good chance it might be an organizational problem and, if not, a HR problem (which is not necessarily related to a specific incident).
