So, there are two sides to every coin, and two sides to every skill set in SD when you think about it. We have a great tool in the form of forensics. With forensics we can learn a lot about what has happened to a body and the items on and around that body (hopefully with additional information in the form of details involving the room in which certain crimes are committed in the near future.) With the appropriate tools, an individual can determine who has touched a particular piece of gear, or meddled with a corpse or a crime scene. That being the case, individuals with a high enough level of forensics skill should be able to 'scrub' items, corpses, or crime scenes of available data, in the process ruining the chance that specific details are passed on to those who are actively searching for it. Scrubbing a corpse doesn't really seem feasible, though having some sort of 'dispose' command along with the appropriate tools (sulfuric acid and hacksaw anyone?) might allow people to ICly trash corpses. Although, having a way to disfigure a corpse to the point that it is unrecognizable might allow for corpses to remain but have physical details altered such that fresh corpses are nameless and disfigured of identifying details.
Just a few random early morning thoughts.
