add fingerprints to bullet casings

Description:

When firing a gun, add finger prints to casings that can be identified when using the lab to inspect a bullet in the report.

But add the mechanic that is identical to Scratched Hands from lock Picks to prevent fingerprints.

Reason:

Expand the CID and investigations of PD where evidence is limited.

Time and time again cases go unsolved unless the suspect is apprehended or blood samples are left behind from being shot.
