The KGB are not in existence as government agents or otherwise.
Most ex-KGB are now Russian Mafia. The Mafia has a hand in everything, from legal to illegal sectors of the economy. Most top Mafia members either have or hire people with extensive KGB training. The KGB was sort of a max between our FBI, CIA, etc. witha more "action-oriented" focus than the somewhat passive intelligence gathering of most of our operatives.
