translation.en: The Supreme Court ruled last month that a policeman has to get a warrant if he wants to do prolonged tracking, but the law isn't clear about civilians doing this to one another, so it's not just Big Brother we have to worry about, but Big Neighbor.  There is one alternative that Carol could have taken, very effective. It's called the Wave Bubble.
translation.zh: 最高法院上个月判决，一个警察如果要延长对某个人的跟踪时。 必须得到授权。 但是法律没有明确规定平民这样做会如何。 我们要担心的不仅仅是“老大哥”， 还有“老大邻居”。 Carol可选的另一个做法会非常有效。 它叫做电波气泡。
