  2. Re:Uh No on Bruce Schneier On Airport Security · · Score: 1

    I think you missed Schneier's point, if you RTFA. The approach to dealing with threats should be intelligence gathering, our criminal justice system, and resilience in response to successful attacks.

    Were Schneier an actually security professional, even fairly knowledgeable about the field, he'd know that's just one side of security. (And one we actually are doing.)
     
    But Schneier isn't a security professional, he's a consultant and columnist and a pundit. (OK, I'll grant he's a professional in computer security, but that's not the same thing as physical security. They aren't even close.) He makes his money by getting his name in print pontificating about things he not only doesn't understand, he makes no effort to understand. Were he an actual security professional or even knowledgeable about the field, he's understand that there is a second side to the coin - deterrence. Intelligence gathering and criminal justice doesn't deter, but visible security does. That's why stores have silent alarms and physical barriers. That's why military security at bases housing nuclear weapons have gate guards - and an armed and short tempered Marine company inside. Real security has multiple layers, with backups, and works as a concerted whole.
     
    You also cannot (as Schneier haughtily and ignorantly does) discount the positive effects of visible security. If people feel secure, they keep flying. As a google chunk of the US economy depends on those passengers, keeping 'em flying is a good thing.
     
    Now, I'd be the first to agree that the TSA's response to the latest attack is wrong headed, but to roll back physical security to pre-911 levels (as Schneier proposes in the article) and relying only on law enforcement methods is just stupid.

    Actually, that's not quite right. Many of those communities 'sprung up' because either a) the railroad built maintenance infrastructure there and the workers had to live somewhere and a town grew up to support them, or b) the railroad planted colonies on land they owned on the theory that the population thus planted was connected to the outside world only via the railroad and would generate passenger and cargo traffic.

    In my community the police blotter isn't published daily, but the local paper does print selected excerpts.) In fact, it appears, from your own link, that any portion of the blotter being published [by the police] is scarce. If they are published, it's excerpts by the local media. (My local paper doesn't print names in their blotter excerpts, only in full stories.) Or, in other words, "public record" != "published".

    Cruise ships depart US ports almost daily, airliners depart from where in the US every second, rail cars by the thousands are in motion day in and day out - and nobody cares. It's all routine. If space travel and access is all routine, then that's usually considered a sign of maturity.
     

    We don't need more frequent launches, we need a manned space program that actually makes progress if we want people to get excited about space travel.

    You state that as if not being able to make progress without getting people excited was a fact, as opposed to the opinion it actually is. Research ships leave US ports routinely, and there are probably a thousand or more science teams in the field in the US at any given time. (Well, maybe not this week with the holidays and all.) All of this happens almost completely without public notice, and the lack of such notice impedes progress not at all. (And that doesn't even touch on the [probably] tens of thousands of lab bench bound research projects or researchers toiling away in libraries and archives.)

    They're trivial to build, once you've done the non trivial tasks of designing them and creating the infrastructure to obtain the fuel. But the real reason the American's didn't test the design is that they used a generous amount of design margin to ensure it didn't need to be tested.
     

    A rogue state that just wants to build a "few" nukes could easily make these. As long as the intended use was terrorism, and not strategic ICBM warfare, then the weight is not an issue. Several analysts have pointed out that one could simply ship such a weapon to any major city in a standard shipping container, and it's unlikely to be detected, as the gamma radiation scanning devices installed in US ports are trivially defeated by several types of shielding, including the natural Uranium casing used for most gun type bombs!

    The problem with the above is multi fold: First, if a state is using them weapons, then it is warfare rather than terrorism. Secondly, letting a nuclear weapon leave the tight control of a highly trusted group of people is an exercise few dictators are likely to indulge in. (There's way too high a chance that the weapons will be used against them.) Lastly, no gun type bomb uses natural Uranium. (Fission reactions don't produce neutrons of the energy range needed to fission raw Uranium - that takes fusion reactions.)
