RFID tags in bullets

2007-04-19

It might not help much, but it would be one more element in the forensic trail. Also I’d be curious to see how many bullets bought by governments actually ended up in the chests of innocent people.

Whilst I’m briefly on this topic, why don’t we record the characteristic striae when a gun is manufactured? (probably because then the database would be too large).

    The NIBIN has 120k fingerprints. There is a campaign to register every new firearm in the US on it. http://www.bradycampaign.org/facts/issues/?page=ballistic

    How about very small changes in the composition of the metal used to make bullets? Each pack of bullets would then have a unique alloy fingerprint.

    Might not be feasible from either a chemistry or manufacturing perspective. Would make the sales process more tedious, unless you had to use a registered gun owner card when buying bullets.

    I’m sure the metallurgists would never stand for the government mandating chemical changes to their Precious Metals. But the Carbon dating guys can count individual atoms of Carbon-14, so mixing in radio-isotopes in tiny amounts (1e-12) could work.

    It reminds me of various schemes to add coloured plastic particles to explosives. Apparently this and its generalisation is called a Taggant.

    How about an RFID installed in George Bushes a**hole (no – not tony blair) and perhaps letting the secret service test out new ‘lead bullets’ ‘buck shot’ and ‘silver bullets’ on the werewolf to see whether it can be killed before it wages war on every Muslin country and we all end up on a jihadists fatwa list.

    Ban guns, guns DO kill people not the backward ‘logic’ of the USA gun fraternity, to have the right to ‘bear arms’ – don’t they know the civil war has ended or are all yanks really so thick and stupid, when you consider that out of a population of some 260 million there is a penal (penile?) population of some 2 million ‘inside’ you know something is wrong with the gun culture, we’re starting to have an increase here with the black-on-black ‘you disrespected me’ gun crime.

    RFID tags in bullets would make it REAL EASY for the goons to drive by your house and know exactly how many bullets you had on your property, as well as what caliber. Holy Invasion of Privacy, Batman! Between this and the GPS coordinates of your house, it would be real easy to have “surgical strikes” on certain highly-armed citizens who do not agree with Lord Obama on any of a number of issues regarding His agenda.

    Oh puhlease. Surely anyone who lives in a house like that already has an RF screen around their house. Otherwise they can pick up your every keystroke. Duhh.

    The idea is to design the barrel of the gun with a radioactive signature or barcode. That way every normal bullet passing through the barrel would receive a radiation pattern unique to that ballistic device. It would take some moderately high radioactive material to create a print on the bullet that quickly but you probably only need the print to last a day or so. Just enough time to retrieve the bullet from the target. Then you would put the bullet into a dark cylinder lined with photographic film and expose it for a few hours to retrieve the print. Match it to a database of known gun barrels and you’re done.

  8. drj11 Says:

    @JoJo. Silly. The gun barrel already possesses a uniquely shaped electrical field that marks each bullet with an identifiable fingerprint as it passes down the barrel. Moreover the identifying marks are easily inspected using commonly available visible spectrum radiation and can be archived using ordinary photographic equipment. We call them stria.

  9. JoJo Says:

    Yes, then we are talking about different things. To identify matching stria you must first obtain the suspected ballistic device. Plus, the gun barrel and “fingerprint” made can change over time as the barrel is fired repeatedly. I’m suggesting a way of manufacturing the ballistic devices to put known and intentionally coded fingerprints onto normal existing bullets. That you only need the bullet to find the match.

    I’m not sure how knowledgeable you are with firearms, but you do know people can make there own bullets, right?

    And friction paste can change the profiling marks…

      I guess in principle I knew that. What’s your point? We can’t trace hand-made bullets easily, so we shouldn’t bother with mass-produced bullets?
