And be sure to open it -only- at the crime scene. If the investigator could grab a sample of the same mix of DNA at some other location that the suspect visits then they'd have a clue that the scene was tampered with. As always, you must look at both 'traffic analysis' and 'signature analysis'. > Major Variola's Brand Homogenized Human DNA Some other factors: - With sufficient motivation it would be possible for the police to keep a running sample of most public places. Exactly what would drive such a utility function isn't clear. Perhaps an assassination of a high dignitary or major theft. If they could track a suspects last few days it would be possible for them to take comparative samples. - Never spit or otherwise leave phsical evidence in public (ie trash recepticles as public eating places) so that a sample can be taken without a search (at least technicaly it wouldn't be a search). There are cases of cops following suspects for several years and finally catching them by simply grabbing a spit sample off the sidewalk (there is a real world example I posted in the archives a couple of years ago). - If you're going to commit crimes where physical genetic evidence may be problematic then be sure to have taken a good shower and a fresh haircut (if it wouldn't be incriminating). Make sure your clothing is freshly washed and has been touched by nobody who has regular interaction with you. This means a clothes cleaner you don't normally use (don't use a credit card or a real name/number). If possible get somebody else to pick up the clothes (there are cameras everywhere). - Wear complete coverage clothes, sort of like those sleepers you wore as a kid only with gloves and booties. This would include a face mask. - Wipe the outside of the outfit off with something that is a very good agent at breaking down DNA, carry a spray bottle of this same agent. Spray it liberally. - It might be worth making the outside of the suit slightly tacky so that it tends to pickup instead of shed material. This may imply wearing several layers and shedding them once in a while. - Be sures that there is nothing in ones background that would indicate they have necessary knowledge, motivation, or ability in this regards. - This all implies a lot of preperation and time that is not constrained. Having large gaps in ones schedule at convenient times would be indicative. It's worth noting again that one of the major threats to anyone building such a database of genetic data is the continued denial of that same technology to the public at large. If genetic technology expands until it's reasonably easy to have scans and splices done then keeping a databank of individuals DNA is worthless. Personally, I believe that this is the reason that cloning and such are being hounded into illegality by secular authority. Once somebody has a legally recognized clone walking around (or clones that are unknown or unregistred) any such DNA evidence is worthless. -- ____________________________________________________________________ We are all interested in the future for that is where you and I are going to spend the rest of our lives.
