Yep, if he had continued, he would have at very least been able to finish off all the injured. So the death toll would have been anywhere from 500 to 1,000, or even more. It's not surprising though. These guys always stop, when they want to stop. They are never stopped. They can't be stopped, and LE doesn't even try to stop them. Because "officer safety is paramount". So cops just go to a staging area out of range of the shooter, and wait there for the gunman to get tired and stop shooting. We haven't even seen anything close to the worst we are going to see in the future.
