"We will just exercise a level of surveillance that will clearly ensure that nothing like this happens again,"

VOA: standard.2010.01.23

If we only ask these questions, we will miss,literally miss an important part of reality, just like you missed the children on the bus in the exercise.

如果我们只问了这些问题，就会错过现实中很重要的部分，像你们在练习中没看到公车上的孩子一样。
