Yes you might be surprised but the police keep notes/tabs on the community. If you call something in or otherwise inform them you will be in the system which would alert them.
Indeed, seems plausible the police keep tabs on individuals in the community (yay for the privacy implications there) but the point of the gp is the cops have a disincentive to take X citizen's statement "Hey, I'm doing nothing but someone might swat me" since that's what a criminal would say. ("There is no 'do not Swatt' list" is a great tl;dr;)
I mean, if there was a special thing someone could do before hand to keep the cops from showing, guns blazing, when they thought it was appropriate, nearly everyone would do it and that would be a problem if such a response was appropriate.
So there's really only approach - make cops dial back on the use of deadly as their default. That's the only thing, there's no way to get a special "no don't shoot" card for random in random suburb, much as people might want it. Well, unless you are a neighborhood with money, then it's different.
Edit: And don't think the cops would cough-up their notes on house X for the same reason. Obviously, if the cops even admit they are keeping those notes, of course they become subject to all sort of controversies. Whether they're constitutional would come into question, etc.
In the heat of the moment (police suddenly getting a dispatch for a murder / hostage situation at a local residence) I hardly believe anyone involved is going to have the time to thumb through notes like that. Maybe in a really small rural community but I can't imagine there would be much chance of things going properly in any sort of larger municipality or city.
Are these notes available as part of a freedom of information act request? Because one should be able to have written verifications these notes exist for when the inevitable breakdown in communication occurs and the note is not passed along to first responders on the scene.
