By Fred Burton The business manager of Russian state news agency Itar-Tass, Anatoly Voronin, was found dead in his Moscow apartment Oct. 16, reportedly with multiple knife wounds. The incident is the latest in a string of killings involving high-profile victims over the past month that underscore the challenges and very real dangers of doing business in Russia. Many of the risks — from organized crime rings, skinheads, corrupt government and security officials or random street violence — have long been evident, and arose as Russia reinvented itself after the fall of the Iron Curtain. These core issues, however, often seep down into daily life in ways that are not always easy to anticipate, and yet can impact business operations and finances in serious ways.
