我 11 岁时因接触密码学而留下 FBI 记录（2015）
I got an FBI record at age 11 from dabbling in cryptography (2015)

导读
这是斯坦福工程师 Les Earnest 的个人回忆：他11岁时因对密码学/加密通信的兴趣，被 FBI 建立档案。文章讲述这段调查如何发生，并引出对政府监控、档案误读和个人隐私的反思。
为什么经久不衰：它把荒诞的童年经历与监控权力、档案误读联系起来，几十年后读仍切中隐私与执法过度的问题。
HN 评论精选
隐私不是有秘密的人才需要，监控权力可能被滥用并误伤普通人。
这个故事（假设属实）很好地说明：即使你觉得自己没什么可隐藏，也需要隐私。和平时期机构只说在找“恐怖分子”，但一旦局势变化，就可能根据浏览记录、消费习惯和某个探员的直觉或算法把你列入名单。

This story (assuming it's true) should serve as an excellent example of why you need privacy even if you think that you don't. In peace time the NSA is only looking for "terrorist" and leaves everyone alone, but in case of war they would start creating lists for any and everything. All it takes is one "tough" agent trusting their gut feeling/algorithm based on your browsing history and shopping habits to put a target on your back and you are done. EDIT: Replacing "if there's any truth to it" by "assuming it's true". I did not mean to imply that the author made up the whole story and thought both expressions were equivalent.
间谍机构会用自己的世界观曲解一切，监控档案充满误读。
一位在东德留学的人在柏林墙倒塌后申请了自己的斯塔西档案，发现里面充满误解：她为挑战者号爆炸难过，却被情报人员困惑，因为他们认定航天飞机百分之百是军事项目；她调查一位亲属的下落，档案却把她写成在联系“潜伏特工”。她拿到了斯塔西档案，却始终拿不到自己的 FBI 档案。

A person I know studied in East Germany in the early 80s via a very limited exchange program. After the wall came down, she requested her Stasi file. It was fascinating what was in the file - lots of misunderstandings and misinterpretations. For example, she was upset when the Challenger exploded, and this mystified the Stasi informers who had previously identified her as a pacifist (in their minds, the Shuttle was 100% military). Similarly, she was trying to research what happened to a relative who had remained in Germany in the late 30s, and whether she had died of natural causes or been sent to the camps. The Stasi file was filled with speculations on the details of this "sleeper agent" with whom she was trying to establish contact. All this to say that from the mindset of a spy, everything is spy-craft. Everyone's world-view shapes their interpretation of events and reality itself. Was the shuttle a military venture? Partly. Was it also a tool for science? Yup. But the functionaries who looked at her data in the heat of the cold war certainly couldn't see those distinctions. For what it's worth, she was able to get her Stasi file, but has never been able to get a copy of her FBI file.
政府会为小事投入大量人工调查，监控欲望和误伤都很荒诞。
文章里说：“我们通过查遍圣地亚哥地区所有验光师的档案，根据处方追查到你的儿子戴的眼镜。”难怪政府机构渴望监控整个互联网。另一位探员还提到，调查一起“扯下并踩踏美国国旗”的案件花了很多钱，查到最后才发现肇事者只有四岁。

"We traced the glasses to your son from the prescription by examining the files of all optometrists in the San Diego area." Wow, no wonder government agencies salivate at the idea of being able to monitor the whole Interwebs. I know they now have orders of magnitude more data to process but still... that manual process must have been expensive and boring as hell. I guess as an agent you would need to convince yourself that this was actually a very important task of defending your country or something. Otherwise I can imagine going crazy just doing this stuff for nothing... Edit: Another quote I found amusing: "The friendlier one eventually described how much it had cost to investigate another recent case where a person was reported to have pulled down an American flag and stepped on it. Only after the investigation was well under way did they learn that the perpetrator of this nefarious act was only four years old."
相比过去，今天的执法更直接，电子档案也让旧事更难消失。
这类“简单年代”的故事很好看，但也说明世界变得更具攻击性：FBI 上门已不再是能一笑而过的童年趣事，电子记录不会忘记旧事。过去学校、家长参与其中显得“可爱”，现代执法却会直接把孩子从课堂上叫走“聊聊”。

These stories from more simple times are always a great read, but for me they illustrate exactly how different and more aggressive our world is. Sure, they were rounding people up and putting them in camps. That needs to be mentioned. But visits from the FBI can no longer be waved off and childhood fun. They really do come back to haunt you. Being investigated is far less dangerous than falsely claiming that you weren't. In the past this would go undetected but today's electronic paper trails don't forget such things. They will notice. The involvement of the school officials, even the parents, is also cute. Modern law enforcement doesn't hesitate to go strait to the kids. It is not unusual for a cop to pull a kid out of a class for a "chat" that could see them jailed. Parents often only hear about such things long after the fact. The image of FBI agents in a black limo is precious. That is intimidating FBI man 101. They still do the 'parked in the driveway reading notes' thing today, but only where they don't feel under any threat. If there is any potential for a firearm at the location, or any hint that the suspect is in any way dangerous, they don't hang around as potential targets. If you see them doing the parked thing, wave. Say hi. Or don't. To intimidate they must first be seen. They will keep up the act until someone notices them. If you really want to make their week, get in your car and drive away. They love a good slow speed "chase" before confronting you somewhere out in the world.
