The investigative project and databases

I have started working over the investigative project. And one of the most important things for me now is to understand the structure of ownership of several companies, based in 7 different countries.
I use LexisNexis database and some of US state public datadbases as well as Russian resources.
And I can see the difference.
It comes from Russian "Personal Data Law". Unfortunately that law is not excellent. So a lot of information about people, shareholders, directors you can legally get in US or in Europe, considered to be illegally obtained if the same will be done in Russia.
In Russia even the date of birth of the company founder is considered to be not public personal information. And you can not get it without a person agree.
So in the information officially obtained through tax inspection you will never see d.o.b. and address of the guy who settled the company, but just the name.
Of course under such circumstances a lot of people use illegal databases from the black market.
The result is quite the same as in USA or in Europe - people in Russia do have access to the information. But the black market benefits from it because of the crazy law.
Certainly those Russian officials (from law enforcement, tax inspections, customs service etc) who illegally trade databases are quite happy.
It's a paradox, but in Russia where there is a lack of public information the citizens feel themselves less protected by the state, because even texsts of telephone conversations can be illegally purchased.
