I don't disagree it would be nice, but with the functionality and the way Waze is different, on purpose from other apps, is that if someone gets the prompt for a camera and taps Not There, then it is likely others will do it too, and within a day, the camera is Unapproved and no one will get the warnings again.
It is better to simply mark these, for now, as Police, because that's who is operating them. In the future, perhaps Waze will have another type of option for mobile/temporary speed cameras where tapping "Not There" will simpyl remove the notification of that camera for other drivers for say, 8 hours. Problem with that is, if it gets set up within that time, then others will come along and Add another camera from the app and then the map starts to get very messy.
