Reading the past news from Romania would be enough for a research, the 'small fish' generally get convicted for 500k-5M EUR the big ones never get caught. You can google "romania 30 years of democracy" to get a background of the country and some information and then continue with all the material from 'recorder', most of the bribes come in form of contracts 'clanul marelui alb' is another good documentary centered on the corruption inside the Romanian Orthodox Church and how the bribes and kickback works.
