You may recall that, in the wake of Omar Mateen's attack on the Pulse nightclub in Orlando Florida, attention focused briefly on the killer's wife. Noor Salman told authorities that while her husband had been getting increasingly violent towards her - and had made vague references regarding his desire to carry out a jihadist attack - she had no specific information about his plans. She claimed he was abusive and dangerous, but that she never had any knowledge of the violence he would eventually perpetrate.
