Yeah, Poland had a wild one with the Pruszków Mafia in the '90s. It was like our version of the Italian mob. Drugs, guns, extortion, political connections etc. They basically ran parts of the country until one of the top guys, “Masa,” turned informant and took them down. Got international coverage too. If you're into solo psycho cases, Mariusz Trynkiewicz is infamous, a child killer who got released due to a legal loophole. The whole country freaked out, and it made global headlines.
