*Dial 1-9-1-1
*Dial 9-1-1
*Barricade and stay on the line with the dispatcher.
In THAT order.
Andy no disrespect to you and others as this is good advice in theory.
But in my application 911 does not inform the police officers of enough information. They spend multiple times asking the same data over and over. They argue with you about your location and other facts.
But if you Call them and then hang up. They will call you back and treat you with much more respect as they now think you are in trouble and someone else forced the phone off.
