First of all thanks for your replies. Keep it up!
 I need more advice and I'll try to be more specific.

The focus here is to describe the state of the art on both sides: from a chainanalysis perspective analyzing the tools and on the other side the regulators, law enforcement, etc.
I know that many companies have developed proprietary tools.
AFAIK chainanalysis is not performed on a blockchain, it's too slow and inefficient. GraphDB or other NoSQL DBs in synch with the blockchains are used to achieve a higher level of efficiency. 
Are there some papers, research, github repo, tutorials, speeches, ... to deepen my knowledge?
I don't deny that my final aim would be to propose the content for a chainanalysis course.
What would be in your opinion the structure of such course?
