In the days before there was a Ministry of Magic to regulate the use of Dark Magic, duelling was usually fatal.

在魔法部开始对黑魔法的使用进行管理之前，决斗通常都是致命的。

And if we're going to regulate, it's going to be regulating the use, not the technology itself because the technology is here to stay.

如果我们要进行监管，那么将是对使用的监管，而不是对技术本身的监管，因为技术是要被保留下来的。
