Eddie Molloy wrote a very interesting Opinion Piece We must stop blaming " We must stop blaming ‘systems’ for shameful human failures " :
"The “systems failure” explanation has been used repeatedly in recent years in Ireland as a convenient fig leaf to enable individuals who were ultimately responsible for catastrophic institutional crashes in all sectors and individual human tragedies to escape accountability. "
I have to agree with him in the points he raises. Once the system is blamed then there is never an actual culprit.
I recommend reading the article.
