Why Are Putin's Enemies Dying?

"An expert on Russian intelligence was shot and critically wounded in front of his home in suburban Washington, D.C., just days after he charged that the Russian government was behind the death of former KGB agent Alexander Litvinenko.

Paul Joyal, who works for a Washington-based government consulting firm, was shot on March 1 by two men in his driveway.

The shooting raises suspicions of Russian involvement, given that critics of Russian President Vladimir Putin — journalists, politicians, and others — at times end up suffering violent deaths."
