If doing something wrong gets you T&B with the CP you are more likely to hide errors. This will lead to the the same error probably being repeated, probably leading to more accidents. I haven't done the math myself, because I am a line pilot, but the fact that there is a very positive correlation between just culture and safety makes me think the CP should stay in his office by himself. The safety department will look at what happened, and if the pilots made errors, they wil be retrained, and if procedures were wrong every pilot will be retrained. Naming and shaming does not prevent the stall that already happened, and will definitely not prevent future stalls....
