Cuba's former ambassador to Belgium, who later spent many years in a Cuban jail as a political prisoner, now 76, writes this very moving New York Times op-ed, A Prisoner Becomes a Warden. It's about prison life in Cuba and about Castro. Here's a quote:

Four months ago, 75 brave Cuban dissidents were rounded up and two weeks later sentenced to prison terms of up to 28 years. Unlike us so-called Moncadistas, today's dissidents did not use violence. Their "weapons" were typewriters, cameras, radios and tape recorders. They are writers, doctors, lawyers, economists, teachers, peasants and human rights activists who believed, naïvely, that their ruler and former revolutionary leader would at least tolerate the Universal Declaration of Human Rights (of which Cuba is a signatory) instead of jailing people for possessing and distributing it.

Lately I have been reflecting, after 50 years, on trial and punishment, on the tragic contrast between Fidel Castro, inmate, and Fidel Castro, prison warden.
