Security at the Taj Mahal hotel in Mumbai was temporarily stepped-up after terror threats were received, but even if they remained in place, “it could not have stopped” the three-day attack, the chairman of the hotel’s parent company conceded to CNN on Saturday. “It's ironic that we did have such a warning, and we did have some measures,” Tata Group Chairman Ratan Tata said. The terrorists—who killed 195 people across nine sites in India’s financial capital—entered the hotel through a back entrance. "They knew what they were doing, and they did not go through the front. All of our arrangements are in the front," Tata said. “They planned everything—I believe the first thing they did, they shot a sniffer dog and his handler. They went through the kitchen."
