Re: Fifth Amendment shields child porn suspect from decrypting hard drives

I wonder why people place themselves in a position where it's possible for them to decrypt the drives under coercion. If I wanted to secure something and I thought that I might be under coercion at any point, then I'd stick part of my key files on a system that would delete them if it didn't get the all clear, and have another part that I could destroy in an off hand manner - maybe by smashing a USB key with a hammer…

Isn't destroying evidence obstruction of justice?

I don't know, though I believe so. Burning your keys seems the most likely to count (unless done by some automated mechanism). The time thing I'm not so sure would count though.

A) Are the encrypted files actually evidence of an offence -- without decrypting them how can that argument be made?

B) Do you encryption keys count as evidence if the passwords in your head don't, and if the passwords in your head do count as evidence then how can not handing them over not count as obstruction of justice?

C) Is there a more general case that can be made such as you don't have the requisite mens rea to be guilty? I believe the terms go something like:

"Whoever knowingly alters, destroys, mutilates, conceals, covers up, falsified, or makes a false entry in any record, document, or tangible object with the intent to impede, obstruct, or influence the investigation or proper administration of any matter within the jurisdiction of any department or agency of the United States or any case filed under Title 11, or in relation to or contemplation of any such matter or case, shall be fined under this title, imprisoned not more than 20 years, or both."

If you just have a general commitment that you're not going to turn something over if under duress, does that count? And, if you can't do it and actually are guilty, is obstruction going to get you a lesser penalty anyway?

I imagine this is why encryption doesn't count as obstruction, since you have a general commitment that your stuff be difficult to read by anyone, rather than a specific grudge with the police.

By way of mitigating your risk, you might even be able to tell the police, in recorded interview, that you needed access to a computer in the next - whatever time period - to preserve the evidence that will prove your innocence. I doubt some low-level investigator, who probably doesn't understand the first thing about computers, is going to get you access to a computer in a reasonable time-frame, so by the time they've decided one way or the other it will be too late. I don't know how interview recordings work out in terms of evidence that the defence has access to though.

It's really something I suspect you'd have to talk to a local lawyer about if you wanted a reasonable answer.

Question- I had a idea about how to make this type of punishment non feasible. Replace the standard truecrypt bootloader with one of a design that has a 'self destruct' What I mean by that is, when you turn on your computer and the boot loader is initialized it actually deletes its keyfile from disk and only keeps it in ram. If you dont enter the correct password in xxx minutes or if you restart the computer, that da…

You'd probably need to hide custom firmware in the drive to stop them from simply copying the whole thing. And if that became common they'd just start pulling out the platters and reading them in another drive.

> Good. Better criminals abuse the system than the system abuse people. That's a trope. In reality, the justice system is about striking a balance between the need to preserve order and security and the need to protect peoples' rights. That's why the Constitution uses "balance-y" words like "reasonable" when talking about 4th amendment rights. > I don't trust your friends view of clearly guilty, sounds like bias to m…

what a dangerous precedent you are setting, PD friends acting as judge and jury. Laws change, and there are often subtleties to a law that make rash statements made by some PD friend with likely no more than a GED about "clear guilt" absurd. Even the simplest of laws aren't clear when looked at in detail. This is why we have advocates with specific knowledge in these areas, and why judges hear briefs explaining the n…

> what a dangerous precedent you are setting, PD friends acting as judge and jury.

Nobody is acting as judge and jury. PD's are charged with zealously representing their clients just like any other lawyer, and the ones I know are extremely committed to their jobs (many turned down six figure jobs in private practice to work for state government salaries and defend poor people). They fight hard for their clients, even the "clearly guilty" ones. But that doesn't mean they're not allowed to make observations about the nature of the world.

> Laws change, and there are often subtleties to a law

We're not talking about subtleties here. We're talking about people who rob a liquor store, have people see them do it, have video evidence of them doing it... That's the bread and butter of the criminal justice system.

When you see edge cases in the news and rant about how broken the system is for not taking even more measures to protect the innocent, remember that the vast majority of people who go through the justice system really did do the crimes they're accused of committing, and that factual state of affairs influences how the system is structured. If a lot more of the people who come up before judges each day were innocent in fact, the system would be structured differently.

In reality, forensic data people tend to just pop the drive out of the machine and connect it to a specialized machine that can clone the drive, whilst ensuring there is no write capability, so it is guarenteed to not modify the drives contents. This is done to preserve the "chain of custody", so the investigators can't be accused of fiddling with the evidence.

I think that the only way to do it would be to have something like a fully RAM disk, that is erased when power is lost. But this is problematic because of power outages, so you would be tempted to use battery backups or something, which would in turn make the system transportable, and more likely to not be deleted.

I guess in the case of the article, it was TSA agents, so your proposed system could do the trick with incompetants.

The trouble with fighting for human freedom is that one spends most of one's time defending scoundrels. For it is against scoundrels that oppressive laws are first aimed, and oppression must be stopped at the beginning if it is to be stopped at all. -H. L. Mencken

> People who clerk have a skewed view of the judicial system compared to someone who has been convicted. I'd argue it's a much less biased view that incorporates more and better information.

I am pretty sure clerks are seeing only a fraction of the people who were arrested or convicted, and that that fraction is strongly biased towards people who have money to spend on lawyers. The overwhelming majority of the millions of prisoners we have in America never had a trial. I do not know where you got the idea that our criminal justice system is serving its purpose. It may be great at putting criminals in pri…

> I am pretty sure clerks are seeing only a fraction of the people who were arrested or convicted, and that that fraction is strongly biased towards people who have money to spend on lawyers.

The bulk of nearly any judge's case load is criminal appeals from run of the mill criminals. They might be pro se, they might have a public defender, they might have a cheap local lawyer, but they're not deep pocketed by any means. Indeed, clerks see a skewed picture of things, but one that is if anything skewed towards seeing fewer actually guilty people, not more, for the obvious reason that actually innocent people are more likely to file an appeal than actually guilty ones.

> I do not know where you got the idea that our criminal justice system is serving its purpose. It may be great at putting criminals in prison, but it is meant to protect innocent.

The purpose of the criminal justice system is to protect the law-abiding public by putting criminals in prison. That is its sole reason for existing. An important constraint in doing so is protecting the innocent, but that's not its purpose. If it were, then you could design the perfect justice system simply by never putting any people in prison. But the world has bad people, lots of them, and that's not a tenable option.

You design a justice system the same way you design any system. You pick a false-positive rate you can live with, then design the rest of the system to maximize throughput while still hitting that false-positive target. It's the only sane way to design something that works as opposed to a non-working platonic ideal.

Isn't destroying evidence obstruction of justice?

It depends on the intent. If you create the system explicitly to destroy evidence if the police are looking for it then yes. If, instead, you create a "safe" that as an anti-tamper measure destroys the contents, then no (BUT IANAL).

In the UK, that would qualify as destruction of evidence 9/10 times. Source: Looked into doing something similar to protect confidential information and sought legal advice first.

The stigma comes from an attitude that the judicial system's responsibility is to produce convictions, so it appears that defendants who are not convicted are merely certainly-guilty people against whom the prosecution didn't have the tools necessary to convict. Down this path lies lowered standards for due process and evidence and a higher incidence of false positives.

the judicial system's responsibility is to produce convictions No, that's the responsibility of prosecutors. Trial courts are 'finders of fact,' whether or not those facts suit the prosecution.

Please read more closely before replying. You missed rhizome's point entirely.

This is one of those issues that leaves you arguing with yourself ... I'm 100% against child pornography (or really the exploitation of anyone), but 100% for rights to privacy, both digitally and in "in real life". We can only hope that if this suspect is guilty, they find evidence that can be obtained without violating his rights ... and of course if he's innocent, I hope he avoids the stigma being a suspect might b…

This is not about privacy, it's about self incrimination which is far, far more important. You can be compelled to testify under oath for many reasons none of which involve doing anything wrong. When you testify under oath, you must answer the questions asked truthfully or face unlimited jail-time for contempt. The fifth amendment is the only form of protection you have from being called to testify and being grilled…

Unfortunately it seems that discovery and testimony have become increasingly conflated over time. I don't buy the arguments that compelling someone to decrypt something is discovery rather than testimony. The precedent that tips the scale between discovery and testimony hinges on whether the prosecution "knows" that the data is there, which is bogus to begin with precisely because the supposed data is encrypted. They couldn't possibly "know" what is there without compelling the defendant to decrypt. And if there is already "sufficient evidence" to tie a defendant to supposed encrypted data, as has come up in certain cases, than there is no need to compel the defendant to decrypt in the first place. Provide your "sufficient evidence" to the court and let the judge and jury do their jobs.

I think precedent leaned this way precisely because people understood that otherwise, guilty people would definitely walk. And they couldn't have that, even if it meant that the spirit of the 5th amendment was violated.

This is the same scare tactic they always tout to take away your rights with. The Canadian government said the exact same thing last year while promoting their internet spying bill. It's garbage.

Whether there is an agenda by lobbying groups or other interests in increasing surveillance or just federal agencies need more power and funding to "protect", the effects are predictable -- make a showcase example using some horrible crime (terrorism, child pornography, in the past maybe communism or drug war related). It doesn't matter as long there would be maximum rage against the perpetrator and nobody in the public sphere would dare defend them and still remain standing as a public or political figure.

People like stories and laws are slowly eroded by scary stories. Joe-Smith-child-pornographer and Molly-Johnson-the-terrorist cases are brought as examples of the evil of encryption and anonymity. It is very easy, the script is always the same.

Again not saying there is top down shadow conspiracy to all this just how the constraints and incentives are set up these things emerge as a result.
