That's all it is, but that's all that's needed because what it does is it takes the tacit information available to the whole population -- everybody knows where the violence is, but no one person knows what everyone knows -- and it takes that tacit information and it aggregates it, and it maps it and it makes it public.
那就行了，那就是所需要的了。 因为它所做的就是获取 全人类那些不为人知的隐形信息- 每个人都知道暴力发生在什么地方， 但是没有人通晓所有信息- 所以这个程序就是将获取的那些不为人知的隐性信息汇总， 再到地图上定位， 最后公之于众。
