The interrogation of Abdul Ghani Al Khanjar followed a pattern.
First, Bahraini jailers armed with stiff rubber hoses beat the 39-year-old school administrator and human rights activist in a windowless room two stories below ground in the Persian Gulf kingdom’s National Security Apparatus building. Then, they dragged him upstairs for questioning by a uniformed officer armed with another kind of weapon: transcripts of his text messages and details from personal mobile phone conversations, he says.
