  1. Re:Brief time window? on Intelligence Officials Fear Snowden's 'Doomsday' Cache · · Score: 3, Interesting

    An alternative construction is possible. You construct a clueless agent. It reads the current time, fills the MSBs and LSBs with 0s to select for time range, possibly with logical shift right, then performs: hash(hash(truncated_time)) XOR hash(hash(given_password)), checks against its internal value (same construct), and uses hash(truncated_time) XOR hash(given_password) as the actual decryption password. This sort of thing is trivial to implement (and has been implemented).

    From an attacker's point of view. Suppose you now slice the time of day up into a short list of fragments you can hash. Now you have a list of hash(hash(truncated_time)) and potentially hash(hash(truncated_time)) XOR hash(hash(given_password)). You XOR each of your truncated time constructions to yield a list of hash(hash(given_password)), and you're back at the original clueless agent problem.

    I'd be slightly more concerned about unauthorized (by the owner) over-the-air updates to my vehicle. What is within the power of one fool to do is also within the power of another. If I can't disable or refuse an automatic upgrade, I'm not using it, period. Then again, my car is mostly mechanical, and I like it that way.

    This is a form of the No-True-Scotsman fallacy. No True Scotsman would install these compartments, therefore if they arrest a Scotsman based on this law, it means they're not a True Scotsman.

    First off, if you DO know about that, lying to a federal officer is a crime, and often in other circumstances, lying to a lesser officer is also a crime. In court, if you say you didn't know about the existence of the compartment and then they find DNA or fingerprints in there that belong to you, you're really up shit creek, even if you broke no other laws.

    The best policy is simply to maintain absolute silence, except to state your name and confirm that you are mentally alert. This is the policy I followed during an illegal search of my vehicle and subsequent interrogation of my passenger and myself. I was let go (nothing to find) but given a ticket for failing to use a turn signal (while driving straight, not changing lanes).

    Silence is golden, especially once it becomes apparent you are being harassed illegally by law enforcement. Too many people can't shut their mouths and just HAVE to explain to the officer, who isn't bound by any restrictions with respect to lying to you. The officer in my case said he was a nice guy and if I'd just hand it over (which I couldn't, as I had nothing TO hand over), then he'd let me go. Well, next thing I know, I'm being physically hauled out, searched, my car is torn apart, my passenger is also interrogated. And to top it all off, I get a ticket for something I didn't do, just so he could save face (there were 3 vehicles at the scene, not counting mine.)

    Save it for the courts.

    Human ability to judge distance without references is notoriously unreliable beyond 20 feet or so. It takes actual practice to determine the size and range of things at a distance (see any scope marked for mils) or a reference (the average person appears X tall at distance Y. However, if you see a car way far away, and it's moving quickly, that'd need to be quite some change in apparent size in a short period of time. Plus, you'd really need a stopwatch for that.

    Sure they do, and I own some rather expensive photographic gear, primarily my baby, a Canon zoom telephoto, which costs several times what any camera body I own does. But that's a lock box, it's not for drugs, and it isn't concealed. None of this is really applicable to the question at hand. Now, if the police arrested a photographer who didn't happen to have his gear in there, and the compartment was purposely built into the vehicle and concealed, then you might have something, but this law still talks about drugs and trafficking, or a convicted felon owning a car with a concealed compartment.

    In Massachusetts, the smell of marijuana is NOT probable cause to search a vehicle, although I have personally experience an illegal search and detention of my vehicle, myself, and my passenger. The State Trooper claimed to smell marijuana (a lie), physically hauled us out of the vehicle, put us in two separate vehicles, ripped my car apart, interrogated both of us, and then let us go (with obvious disgust, as there was nothing for him to find) while giving me a ticket for failing to use my turn signal--despite the fact that I was travelling in a straight line, not turning, and not switching lanes.

    Replying to myself, one last time, since I don't feel like arguing with a defeatist who thinks that everyone should be as incompetent or incapable as them. It is not a question of being able to do it. That's well established. It is a question of dedication, in time, effort, and money. I have bent over backwards and spent years of my life learning to do these things, to purchase and build the tools, to source the materials, to learn the necessary chemistry, and to actually go ahead and do it. It's marginally more complex than making your own PCB, and smaller processes require correspondingly more expensive equipment, different resist formulations, etc., but it is 100% doable for your average educated hacker to do this on his or her own. I'm really fucking sick of being told that I "can't" do something, because I'm not . It's just not true, and I strongly dislike people that produce these bald-faced lies.

    Again, you need to prove intent. And in some states, the possession of "burglarious instruments" is only restricted if used in the commission of a crime. For instance, in my state, Massachusetts, there aren't any laws restricting me from carrying lockpicks, slim jims--you name it, I have it. In fact, a manufacturer of such tools is locally owned and operated. I also took a course from a third-party locksmithing school, and they happily sent me materials without any background checks, but I don't need certification to possess and carry these things.

    Before someone gets on their high horse and bitches, I don't generally carry these tools around, and certainly not to break into anything. I am a member of the Locksport community, and a compartment like this in my car would be generally useful to keep nosy people from stealing my tools (not the first time someone has tried).

    "We apparently caught them between runs, so to speak, so this takes away one tool they have in their illegal trade. The law does help us and is on our side," says Combs.

    Apparently? So, you own a house, and your wife was away for a week. I'm going to slander and libel you for being an adulterer, even if I verified that you didn't have anyone in the house for a week, because you were apparently between mistresses. What a cock-up and an abuse of the legal system.

    The law says it’s only a crime if the hidden compartment is added with the “intent” to conceal drugs, but it also outlaws anybody who has been convicted of felony aggravated drug trafficking laws from operating any vehicle with hidden compartments.

    Can anyone find the arrest record/docket and figure out exactly how they alleged intent, or that he was formerly convicted of felony aggravated drug trafficking laws? Otherwise, this looks like a money grab to me.

    As for the car itself, the Institute for Justice’s 2010 “Policing for Profit” report calculated that law enforcement officials in the state have collected more than $80 million in shared proceeds from asset forfeiture funds. Oh, and the hidden compartment law exempts vehicles being operated by law enforcement officers, so if state troopers can come up with an excuse to use the ride they just grabbed, they may be able to keep it for themselves.
