Why did the officials turn a blind eye to the crime?为何官员对此罪行视而不见？

形容对某件事熟视无睹、视而不见，就可以用这个英文习语turn a blind eye to sth.，在口语中，也经常说成“装看不见”。
　　这是山西虐工事件发生后，国外媒体的一句评论：
　　The same local officials who were now parading themselves as rescuers of trapped workers had long turned a blind eye to the trade.
　　如今，以被陷工人拯救者自居的地方官们，正是长久以来对此交易视而不见的人。
