The Goulston Street graffiti is another example. Sir Charles Warren, afraid of the political ramifications of the writing on the wall, ordered it destroyed against the advice of his police investigators. Whether the writing was done by Jack the Ripper or not, it should still have been documented and examined for elimination purposes, if nothing else. Another major aspect of the crime scene is documentation. Even today this is still done in the form of crime scene sketches.
Detailed measurements locate the precise placement of every item at the crime scene.
Body location and position, locations of any evidence found, furniture arrangements and blood stains are all documented on a sketch. Photographs are taken of everything. Up close shots, distance shots, different angles, different lighting and exposures. It is important to note that you cannot have too many crime scene photos. Today it is easy to take photos with a disposable camera and have the film developed in an hour.
