A special effects grenade shouldn't be able to kill a normal healthy person. They would use that in riot control as well. I wonder what pre-existing condition caused her poor health. This lady must have been health wise a walking time bomb. Ah. yes, that's it. If she would have lived, they should have arrested her for not registering her illness with the police department!
They would have turned her over to the FBI, which would have busted her as a terrorist for the nitroglycerin tablets in her purse....
