There is a technique recently developed in forensic science for
reading the minute indentations left by writing which might help. It
uses a very fine graphite and electrostatic charging and has worked
well showing how documents have been altered. Local law enforcement
or criminal legal offices may know whether this technique is
available in your area.

If this technique is available, I would strongly urge that no
further handling of the labels takes place (and certainly no
rubbing) until the treatment is applied.
