How about, when a corpse is fresh, you can see the wounds on it (example: *corpse desc* The corpse has a gunshot wound to the groin and to the abdomen.)
The more rotten a corpse would be, then you'd need an increasingly high medical skill to determine cause of death. Those with the munitions skill in addition to medical could also find out what the caliber of the weapon was in the case of gunshot wounds, etc.
This would open the way for forensic investigators, and such.
Also, it'd be nice if those with weapon permits had to register their firearms for them to be legal (that's what the serial number is for, right?), and there'd be a listing of weapons along with serial numbers on the Tac-comp when viewing the record of someone with a permit.
