Cell Phone Jammers: Coming To An Event Near You?

DarwinDan writes "The L.A. Daily News has an article about Cell phone jamming to prevent terrorists from detonating bombs remotely. Jamming technology is already being used "to protect President Bush." An interesting quote from the article: "Public safety is more important than public convenience.""

    It's a good thing that I've got my cell phone handy to call 911 with in case I see possible terrorist activity! Oh wait...

    I'm no radio expert, but isn't it still possible that you could simply use some other kind of transmission, rather than cell phones? Say, ham radio, police frequencies, citizen band, or whatever?

    Blocking cell phones seems to me to be what's called "security theater." It's all show to make people think they're safe, and (more especially) that the government is "hard at work ensuring the nation's security." (Blah, blah, blah.)

    This is good theater, too, because it is something that affects almost everybody at an event, so they're sure not to miss noticing the "hard work." Why, it'll be the talk of the town!

    At most, this is 10% security, 90% public relations.

  5. Safety is about mitigating risk by csoto · · Score: 5, Insightful

    Which of these is a far more likely risk factor?

    1) Terrorists using cell phones to detonate bombs (which can be done with a simple mechanical timer far more easily)
    2) Fire, heart attack, drowning, etc. wherein using a cell phone to dial 911 could save lives?

    This is somewhat like banning cars from an area. Sure, cars are a convenient way to move people, but hey, it could also be used as a delivery mechanism for an explosive!

    Hasn't anyone in America clued up to the idea that 99% of the impact of Terrorism is exploiting FUD? In allowing the freaky controlling elements of society to make life impossible for the rest of the sane people, don't you lose so much more?

    And don't give me that "if we can save just one life" crap. If that's the case then ban cigarettes, alcohol and McDonalds. Hell, ban religion and guns while you're at it.

    For goodness sake! Stop letting the terrorists run your lives for you! They're winning! Wake up!

    If they knew what they were doing, they'd just get a java-enabled cellphone, and if it wasn't called within some time gap, and the signal suddenly dropped to 0 because it was being jammed, the phone would detonate the bomb based on that. Jamming is just one more hoop they have to hop through to set off the bomb.

    Good thing the terrorists can't get those, or they could remote detonate bombs even with their cellphones jammed!

    Obviously inspired by Hollywood. So what if they decide to use the frequency that the Secret Service uses to communicate? I guess we better block that too. What if they broadcast a codeword on a talk radio show, and a bomb-laden terrorist is listening on a portable AM radio. Better block that band too. So, to cover all the possible frequencies, it'd have to be one heck of a powerful broadband jammer. I guess that's going to interfere with adjacent police and rescue frequencies because of intermod.

    Look folks, Al Qaeda didn't use cellphone-triggered remote bombs, tunnels under schools, IRC, or even orbiting brain-lasers, or whatever stupid possibility has been dreamed of by the Department of Paranoia. They used box-cutters. I'm fairly certain that whatever choice they make next is going to be a surprise. It's not going to be something that the US Gov't expects, so let's stop trying to list the millions of possible ways and monitor the thousands of possible targets.

    I really wish the hype and paranoia would stop. I used to listen to ("conservative") radio host Monica Crowley, until one night she bleated like a sheep stuck in a fence for an hour about how "we should do everything possible" in regard to airport security. I mean, come on Monica, that's something a 7th grader would say. There's a balance between cost and safety, and nobody in her right mind would suggest spending an unlimited amount of public funds just to make sure we can catch someone who has a box-cutter, because there's a one in a billion chance he might want to also fly an airliner into a building.

    Likewise we have El Rushbo, trumpeting that the fact we haven't had an Al Qaeda attack on US soil for one and a half years is proof positive that Bush's strategy is working. As much as I'd like to believe that, the fact is that it costs Al Qaeda money and takes lots of time to plan an act on US soil. The second WTC attack happened almost 8 years after the first. The attacks aren't likely going to stop as long as we're involved in the Mid-East (as long as we back Israel and pull the strings for the Saudi monarchy).

    So once again, it's not a choice with absolutes. Either we continue our current policy and some of us get killed every ten years or so, or we trade some other lives for our own, and watch the slaughter of the Jews, the Kurds, or some other religious minority that is sufficiently westernized to perhaps believe in freedom, interest on money, rights for women, or perhaps not stoning people to death for breaking society's rules. Or, we pick something inbetween, and successive presidents jump to either side of the fence (like the case now). One thing I can be sure of is that some US citizens are going to have a shot at stopping the next attack, just like the last one. So maybe this time we won't behave like subservient little hoplophobic sheep, and someone will fight back with deadly force to spare the lives of others.
