Sorry is the easiest word to say
I am not a great believer in this modern concept that one person must be responsible for all bad things that happen, and that the best solution to any incident is to sack the person at the top, but neither do I believe that saying sorry solves anything.
I don't accept that from my children, and they are all still in primary school! They have to apologise if they hurt others, but they also have to do something to make it up. As a member of the public, I do not feel at all pacified by hearing 4 rich men apologise. Especially as they don't seem to have any idea what they are apologising for>:(
