Good luck with your project, but many of them just break the transactions using coin mixing or any techniques, how can they get rescued?
Submitting case in police station atleast gives a hope that the car will be recovered, but once bitcoin is lost, it is 100% non recoverable.
The purpose is not to recover money, but to report. For statistical informations, or to track for example chrome malware extensions. You search for a specific address and you know that you are infected.
