How did Carlos Ghosn do it?

The former head of Nissan Motor Co. and Renault SA, who was awaiting the first of two trials in Tokyo, somehow evaded almost round-the-clock manned and video surveillance and heavy restrictions on his freedom of movement to flee to Lebanon.

From there, Ghosn released an email Tuesday decrying the ¡°injustice and political persecution¡± of the Japanese judicial system. The 65-year-old faced charges of financial misconduct and raiding corporate resources for personal gain, allegations he denies.
