I saw it. It seems the Las Vegas police force did an amazing job of catching the murderer (though dead) soon enough. They were there, at Mandalay Bay, in 12 minutes after they received the call. Their chief later said that he studied the videos of the massacre in a hotel in Mumbai, India, where hundreds of people were killed. He learned from it and implemented measures in his department.
