    All emails contain at least some legitimate header info. Forged headers
    are easily identified and discarded. What it boils down to is that the
    sender's ISP can almost always be identified, and law enforcement
    agencies can subpena the ISP to release the sender's true identity.

    How many buildings or stores do you know that have very poor or
    non-existant cellphone reception? I know lots of them. Do they all
    employ jammers? I doubt it, and I think it's mainly due to the
    building's construction materials, or being in a 'shadow' from
    obstructions between it and the nearest tower.

    Quite often, that is an overly optimistic opinion.

    The final (or top-most) 'Received' header is always trustworthy.
    While it is true that much mass spam is now sent through open proxies
    (or zombied/compromised machines), that is usually not the case for
    email that is sent by individuals other than professional spammers.

    I meant in the context of individual messages like the post from
    "Kathleen Carmody", which was easily tracerouted to a server in
    Minneapolis, which generally agreed with her email address which
    pointed to Brooklyn Center, MN. There was not the slightest evidence
    of header forging in that post.

    its not against the law. whether or not it should be or not is a different

    Really? The federal government breaking their own rules, huh. I have a
    friend whose father works for the Fed back home (Cleveland branch). I'll
    have to find out what his experiences are.

    The construction angle is probably the most accurate, as many buildings and
    businesses are putting in passive cellular shields (which are legal, BTW).
    Basically a large metal mesh that disrupts radio signals

    Or maybe just aluminum-foil vapor barrier on the back of the insulation.
    That's been in use since long before cellular telephony.

    No- this is a specific part of the building design with the sole purpose of
    stopping cellular signals.

    Don't forget, that cell phones can be "life-threatening" in certain
    situations. I have seen reports where several major hospitals are
    testing cell jammers in the critical care areas because of the
    danger of having an rf transmitter so close to some of the
    sensitive electronic equipment.

    Many of us have had EKGs at one time or another. Remember how hard
    the tech had to work to get each of the connections just so to pick
    up that VERY SENSITIVE voltage from the muscles being read? Now
    imagine a heart attack patient, or better yet a person who had just
    had a transplant, and one of the contacts is maybe just on the
    borderline of marginal and maybe making a little bit like a diode,
    then key a transmitter close to it, with a signal several orders of
    magnitude greater the ones we are interested in. Think it won't
    have an impact?

    Put up a sign and turn on the jammer.

    Ummmmm- doesn't a jammer operate as an rf transmitter and on the same
    frequency as the cell phone? Wouldn't that make it as bad as the cell phone
    itself......or maybe worse, as it would be operating all of the time?

    Don't know about narrowband protocols like GSM, but in order to jam a
    broadband signal such as CDMA uses, the jammer is going to have to be
    emitting quite a lot of energy across a fairly wide bandwidth (several
    MHz). And it would be immediately obvious to anyone using the debug
    screen on a CDMA phone, when simultaneously the received signal strength
    shot WAY up and the signal/noise ratio dived WAY down.

    I think we went thru this topic before a few months ago. It is an old
    wives' tale that cell-phones can gunk up critical-care equipment. Some
    hospitals ban cell-phones for reasons of quiet, patient-care, and
    logistics - not for fear of killing off patients. In many hospitals,
    physicians routinely use cell-phones in the operating rooms and ICU's.

    Nope. I have never seen a cell-phone cause an EKG blip. On the other hand,
    operating room electrocautery will always zap the EKG monitoring. (OT So
    many things can interfere with the EKG that there is always back-up
    monitoring - like feeling the patient's pulse.)
