Obviously, cops should keep track of which addresses/individuals have a history of making things get ugly. Yeah, I suppose it will be abused/misused from time to time. Welcome to human civilization. Good things are used for evil purposes all the time here.
In the military, they call this intel. If you are the point man on a stick of troops that is about to bust a door in outer Moniraqstan, I suspect you want to know that this address is a known bomb factory.
Is this markedly different from the needs of first responders in civilian life? That the resident has a history of seizures, is suffering from dementia, is an escaped felon?
PS: I would certainly agree that if such lists are maintained for political reasons, that is an invalid purpose. I would want to see evidence of such political use only, however. Like CSD said, does this mean that police/fire/EMS would not respond to the person mentioned in the OP? I doubt it, without seeing evidence to the contrary.
