@tjayrush Can't they do this already?
(government agencies maintaining opaque shadowy records of who's been acting in ways they don't like, that is)
Feels like SBTs would be a step backwards for them, as the target immediately knows they're being watched.
@tjayrush他们不能已经这么做了吗？
（也就是说，政府机构对谁以他们不喜欢的方式行事保持不透明的模糊记录）
感觉SBT对他们来说是一种倒退，因为目标立即知道他们正在被监视。
