Singer stirs up a stampede, gunman fires a shot, US “Deadly concert”can not stop? For artists with long criminal records, the United States is taking this lightly and allowing it to go unchecked is a loophole that can not be ignored. The emergency response after the accident has also repeatedly challenged the bottom line of the American people. The deadliest music festival in the United States is on the rise. Thousands of people without tickets burst through the VIP entrance at a Music Festival concert in Houston, Texas, on Nov. 5 local time, crowding the scene and even causing a serious stampede. Eight people were killed, all between the ages of 14 and 27, and more than 300 were injured, the youngest being 10 years old... it was the worst stampede and performance in the United States, according to the Associated Press
