The arrest of Davinder Singh, a senior Jammu and Kashmir police officer caught transporting arms and Hizbul Mujahideen terrorists to Delhi, earlier this month forced authorities to confront the question of rogue cops aiding terrorist efforts. That point was driven home this week after an encounter in Shopian district saw three Hizbul terrorists killed. One was another former cop - Adil Bashir Sheikh, a SPO (special police officer), who made headlines in October 2018 after an image of him posing with Hizbul terrorists went viral.
