要找出一个平衡点
between tradecraft that's good enough to be convincing

让他的情报工作看起来真实可信
but bad enough to be detected.

但是又有迹可循
One of the easiest techniques makes use of cell phone GPS.

If you know the phone is monitored

如果你得知手机是被监控的

你可以追踪整个城市的电子记录
and it will lead straight to your target.

它会直接带你找到目标
You really think the Russians are tracking this thing?

你真的认为俄罗斯人在追踪这个
Well, if they haven't yet, they will be.

所以我得让事情看起来
like Ivan left this bag of documents behind for his contact.

好像是伊凡给他的联络人留下了这袋文件
I'm gonna dump it in that trash can over there.

我要把它扔在垃圾桶那边
