[Now watch some enterprising law enforcement agency combine the "Digital MP" system with DNA sniffing... --Declan]
********* http://www.dtic.mil/armylink/news/Nov2000/a20001113digitalmp.html Soldiers test `Digital MP System' by Trish Warrick FORT POLK, La. (Army News Service, Nov. 13, 2000) Military Police could see around corners, through trees and in the dark as they tested the Army's new "Digital MP System" this month at Fort Polk, La. Patrolmen wore eyeglass-mounted miniature cameras providing "streaming video" to their partners. Viewing screens in the eyeglasses also allowed the MPs to check the faces of suspects they stopped against digital mug shots of known offenders. Fort Polk's 91st Military Police Detachment soldiers became the first MPs to test the system Oct. 30 to Nov. 3. Representatives of the U.S. Army Soldier Systems Center in Natick, Mass., brought the Digital MP System to Fort Polk. They were joined by members of the Defense Advanced Research Projects Agency and a number of contractor teams wanting to see how the system would work on real soldiers. The Digital MP is a durable, lightweight, wearable communications and information management system designed to help carry out reconnaissance, checkpoint security, anti-terrorism operations and other MP missions, said program manager Henry Girolamo, Natick Soldiers Center. The backbone of the Digital MP is a wearable computer developed by ViA Inc., MicroOptical Corp and Honeywell Inc. and tailored to the mission requirements of the MP soldier, Girolamo said. The Digital MP's support features include a hands-free, voice-operated interface and a battery that provides day-long power on a single charge. It features peripherals such as: * An audiovisual system with built-in miniature camera for face recognition and image display plus a noise-cancelling microphone and bone-conduction microphone/earphone for voice recognition, all incorporated in a pair of normal-size eyeglass frames * A BDU-pocket-sized "military e-book" readable even in strong sunlight or pale starlight (with night vision goggles) that emits no light to give away a soldier's position * An electronic glove that can function like a computer mouse with the e-book and translate hand signals into words on other soldiers' eyeglass-mounted viewers The Digital MP system can connect a military police team wirelessly and in ways never before possible, officials said. The eyeglass-mounted camera provides streaming video, which means "it can transmit to me what another MP is looking at even though I can't see him," said Sgt. Michael Sauer, Special Reaction Team noncommissioned officer in charge, 91st MP Det. An MP making a traffic stop or manning a checkpoint can take live videos which are checked against digital mug shots stored in the National Crime Interdiction Center database, Sauer said, so he's quickly alerted if the person stopped has a criminal record. On deployment, the system can warn him that he's dealing with a suspected terrorist or war criminal. An MP on patrol can use the e-book to quickly help others locate what he sees. "Say he's on recon, looking at the terrain," said Sauer. "He sees enemy tanks." Using traditional methods, the soldier plots coordinates on a paper map, calls the TOC on the radio and another soldier plots the coordinates on another map. With Digital MP, "He puts the icon on the map and sends it to the operations center," Sauer said. With the electronic glove, MPs separated by thick woods, buildings or darkness can still communicate silently with the familiar hand signals for "Suspect armed!" and other vital information. The adapted Nomex flight glove, with bend sensors in each finger and in the wrist, pressure sensors in the index and middle fingertips and 2-degree tilt sensors, renders preprogrammed gestures as words in fellow MPs' eyeglass display monitors. The glove works when the signaler doesn't have line of sight communication with the others and doesn't want to give away his position by speaking, said Sauer. The glove also functions like a mouse with the e-book, guiding the cursor with the tilt sensor and using the pressure sensors as right and left clicks. When silence is necessary, as on patrol, the glove can override the voice-operated system. The Digital MP can be programmed to continuously translate speech from English to another language and vice versa with only a five-second lag. Presently it can handle Spanish, Korean, Arabic, German, French, Italian, Portuguese, Dutch, Thai and Turkish, and officials said they plan to add "militarese" -- translating the soldier's "clicks" into the civilian's "kilometers," for instance.

While it is not as discriminating as nuclear DNA, it is a very powerful tool, especially in terms of excluding innocent people who have been unjustly accused or convicted. Our firm has two cases in which we hope MtDNA testing will help prove our clients' innocence. Further, mtDNA testing can be utilized in situations where the size of the sample is extremely small, old or degraded and can also be used to better identify hairs left at crime scenes which typically are not suitable for nuclear DNA testing. Since the mtDNA is derived from the mitochondria one can actually run the extractions on the hair shaft. It is used extensively by forensic anthropologists, including successful extractions from Neanderthal skeletons. Phil Cormier Silverglate & Good 83 Atlantic Avenue Boston, MA 02110

Incidentally, the name of the film is based on the initials of three of the four amino acids that comprise DNA - Guanine, Adenine and Tyrosine. Cytosine misses out.Cheers Richard

Agreed: 1. there's less of it, 2. it doesn't mix like other things you get from your parents (forensic genetic markers, major histocompatability proteins, immune system genes). All your mitochondria are descendents of those floating in the egg that ended up cypherpunk. However, If there's enough diversity in the mitochondral population you could show that John Doe (or his siblings or maternal line) were there. And there certainly is some variation; IIRC some of the Lucy pedigrees were based on tracing mitochondrial genes. (Besides, you can't copy error free [1], and the mito genes are not *so* 'densely coded' that a point mutation = death, ergo, you'll see some variation) There are probably some bio usenet groups where such questions would be welcomed, and answered by practicioners, quantitatively even. But you asked here :-) Of course, if you were to sequence the whole thing (NOT how forensic DNA analysis is done now, which looks for presence-or-not of short strings chosen because they tend to vary between people) you'd get better evidence --but that's rather too much today (e.g., the entire civilized world is working on sequencing one or two people these days). And if you could sequence that much, you'd probably sequence some of the genes in the regular ol' nucleus. [1] see Shannon on noise, bandwidth, error rates, coding, etc; note that this implies that you'll eventually (in the mathematical sense) die of cancer (ie a few somatic mutations in the right places) if nothing else.

I welcome other views, I don't think there could be many other views. mDNA (as it's called) can produce "results" - you can say that someone is directly related to a 3,500yo skeleton found in a cave (I did a story about this) because as Hugh said the mDNA is passed down from the mother - it lies outside the nucleus of the cell (where the 26 chromosomes lie) and "powers" the cell. For some reason which I don't know it survives long periods after the cell death far better than nuclear DNA. (Maybe because it's not involved in cell death..) mDNA is used to follow the "ticking clock" of evolution, based on how quickly mutations arise. But although you could likely rule someone *out* of a crime based on mDNA, I don't think it would be sufficient - or at least, any decent combo of lawyer and expert witness should be able to argue persuasively that it's insufficient - to convict. DNA in the UK is taken from swabs from the inside of the mouth, which is then used to create the fingerprint from the nuclear DNA. Have a look at http://www.themacdonaldcase.org/accuracy_of_new_dna_test_is_call.htm which reprints a WSJ article from ..it doesn't say when.. about this.
