Emergency dispatchers and police?

For any of you out there who are either emergency or 9-1-1 dispatchers (as I am), have you ever been able to get anyone to attempt CPR when there is a cardiac emergency call? We are quite frustrated at my comm center because everytime we get one of these calls and tell someone we are going to tell them how to do CPR, they always refuse! If your husband/wife/child were dying in front of you, wouldn't YOU attempt it? Some thoughts, please.
