Fingerprint and Databases too powerfull?

[agente scully]

At some point you just need to scan the place and within 1 minute you know who the killer is because of the fingerprint, and it doesn't feel like an acomplishment at all.

I'll take a show that I'm seeing as an example (X-Files), they do use fingerprints and gov database to find who was involved BUT it take some time to get the response back from the labs/database.
This could work really well on this game, a timer of 1 or 2 days to get the results on the fingerprint that you would need to colect with some special item or whatever that would take inventory space for each colected. The database check could be an ally inside the building that make the check for you, but it take time AND is incomplete.
All of this wouldn't change the game that much, just nerf these really powerfull tools that are easily acessible. With this changes, the assassin have more time to kill again and would stop these 1 minute cases, The challenge then would be to find the killer before it kills another victim.

I was kind of hoping the fingerprint database would disappear after the case would close. It would be cool if it was a realism option. After the case closes then your fingerprint data resets. I have like BZ fingerprints now. Almost resetting on C.
