Nooooooo! He was my next door neighbor a few years ago, and I knew him as a person before I realized that I knew him as a hero.

His dogs were fiercely protective of his house, which is perfectly understandable. One day I saw a "sewer cleaning" van behind his house, and I have a hard time believing that's what it really was: https://honeypot.net/2025/03/12/rip-mark-klein.html

This is the sentence I was looking for:

> While we were able to use his evidence to make some change, both EFF and Mark were ultimately let down by Congress and the Courts, which have refused to take the steps necessary to end the mass spying even after Edward Snowden provided even more evidence of it in 2013.

Do you have to be a cynic to pretty much have expected this?

Had the privilege of watching him receive an award from EFF years ago at ETech. Gave a brief speech. Struck me as a gentle man who really did what he thought was right and for no other purpose. It took moral strength to do what he did. I hope he rests easy.

Damn.

I don't know if this started the whole movement or whatever you'd call it for this push towards privacy and the general public knowing about it, but it helped a lot. Before him releasing info about room 641A and whatever else, there really wasn't definitive evidence of any government spying and tampering, and either with the intention of starting this movement or simply letting people know, he was a big push in the right direction.

tldr: he's a w

> who risked civil liability and criminal prosecution to help expose a massive spying program that violated the rights of millions of Americans.

That's how corrupt the system is. You get punished for revealing crimes against everyone.

Who is going to erect statues for him and people like him?

He revealed unlawful surveillance years prior to and of the same gravity as Snowden, but only one became a celebrity. I would love to know the reason for that.

R.I.P.

He was a true and brave whistleblower.

I had the luck of getting a hold of his docs when they were under court seal, and we published them at Wired.

Only met and interviewed him later. He was a gentle man with a moral compass. A rarity even among whistleblowers.

The world is poorer without him.

I’m watching Person of Interest for the first time. It’s interesting watching it today now that the premise, minus 100% accurate crime prediction, is largely a forgone conclusion. It was produced after Klein but before Snowden and does a good job exploring the expansion of surveillance and just how motivated the government is to have a system that tracks everyone. Of course it’s fiction but it’s a fun watch that asks a lot of good questions.

Rest in peace sweet prince. I'll never forget this discovery, it was probably my first realization that whatever is possible technically is most likely being done somewhere to exert power over people.

And in this case most people in tech knew you could split a network backbone, and if you can do it then most likely someone is doing it. But Mark actually brought it into the light.

And that's what we can't forget in 2025, that whatever is possible technically is most likely being done by someone somewhere. Today it would be using AI to oppress people, track citizens, predict crimes, accuse people of crimes they might commit, or whatever your imagination anchored in technical reality can picture.

motohagiography - 10 days ago

A lot of influential people were quietly radicalized by Klein's disclosures and they took that forward in their ventures, careers, and lives. Change takes time, and almost two decades later, I think we are seeing the results of what those early voices in the wilderness were calling out.

I hope on the other side of current bureaucratic reforms we can make a monument that includes Klein and the other surveillance whistleblowers whose disclosures, and specifically whose courage, turned the popular tide against government overreach.

NSA and AT&T (telecom in general?) caught with their pants down not just once, but twice.

All of this heavily publicized yet here we are today with privacy being an afterthought in everyone’s mind.

I hate to say it but the private corporations and state have really made most of the population complacent with wide net surveillance — cameras everywhere, privacy non-existent, “kyc”, “selfies”, social media, big tech creating profiles of users, and data brokerages selling and buying “anonymized” profiles.

Related, I'm rewatching "Enemy of the State" a 1998 film about government surveillance and assassinations and the deep state.

Underrated in my opinion.

Has Gene Hackman (also topical, which is why I am rewatching) and Will Smith.

Mark Klein was just a guy doing his job... until he saw something he couldn't ignore. He didn't have to speak up. He could have walked away, lived his life, and let someone else deal with it. But he didn't. Rest in peace, Mark

Side comment about suboptimal HN commenting or UI...

This post is about someone noteworthy dying, but the top relevant comment is followed by over a dozen screenfulls of text about a sewer inspection van, before you get to anything else.

If you start paging through it, do you close the browser tab in annoyance before you get to any further discussion of the person and why they're noteworthy?

I expect there were 10,000 who knew, and he’s the only one who spoke up. Now, the other 9,999 likely believed it was to thwart terrorism, as this was post 9/11. Maybe those who had visibility into who was being surveyed were checking to ensure the spying didn’t cross their ethical boundaries. Interesting to think of what each individual in the system was considering.

BiteCode_dev - 10 days ago

I'm expecting nobody will do that anymore in the US.

First, those heroes were treated as enemies, then their revelations lead to nothing for the country, and great pain for them.

Finally, I doubt they would be proud of what their country is today and think it's worth the sacrifice.

Where's the best overview of this whole NSA mass spying story, starting from 9/11 era and the beginning of the dotcom boom? Any good books or documentaries?

CaffeineLD50 - 10 days ago

Its not mass spying. The NSA is just making time capsule backups for everyone. Stop being so dramatic.

In a hundred years when it gets published its gonna be the bomb hilarious. Totes.

7e - 10 days ago

The NSA’s Upstream program primarily targeted foreign communications under the authority of Section 702 of the FISA Amendments Act. However, it also incidentally collected data from U.S. citizens, particularly when their communications were intercepted while in contact with foreign targets.

The court cases were thrown out because of congressional action, as they should be, because the entire purpose of the NSA is to spy on foreigners. Thus these programs were legal and this whistleblowing was not, in fact, whistleblowing at all, just leaks of classified information.

Tom Drake, John Kiriakou, Ed Snowden, Mark Klein.

These are people that have shown that parts of the intelligence community are guilty of crimes against humanity and the American people.

Yet every time more evidence comes out, people are so quick to dismiss it as "wacko conspiracy theories".

Integrape - 10 days ago

Does this not count as a political post? It would have been flagged if the title had DOGE instead of NSA.

roenxi - 11 days ago

The tolerance for the US mass spying efforts remains weird. It undermines the credibility of many US politicians around Trump - yes the US public appears to be set to vote in Hitler-equivalents for the forseeable future. No, dismantling the insane spying apparatus is not a major agenda point.

Marry those two ideas together.

neil_s_anderson - 11 days ago

I find it odd how many people automatically assume that whatever the NSA is up to must be undesirable and therefore should be opposed.

I mean, where do you think analysis of plans by terrorists and nation state adversaries to attack our nation and its allies comes from? The raw intelligence data these are based on can only be gathered by surveillance of communications, both targeted and in bulk.

You should all be supporting this, as you benefit from it every day.
