2009年圣诞节，尼日利亚的一位父亲向美国驻拉各斯大使馆警告说，他担心他的儿子会做出可怕的事情来，从而阻止了后者在飞往底特律的航班上引爆一枚炸弹，这就是一个很好的例子。
The Nigerian father who warned the US embassy in Lagos that he feared what his own son might do – before that same young man attempted to detonate a bomb aboard a flight to Detroit on Christmas Day 2009 – is an example of just this.
