There’s a reason ISIS destroys TVs like this one that I saw on the streets of Mosul. There’s a reason they ban cell phones. There’s a reason they go house to house searching for satellite dishes, radios, or any other means of contact with the outside world. In cities like Raqqa, ISIS’s de facto capital in Syria, punishments for being caught with a phone include public whipping and having your hand cut off.
It seems the more territory ISIS loses, the more paranoid they become.
