Maybe we should move beyond binary thinking here. Yeah, it's worth sending someone to investigate but also making some effort to verify who the call is coming from - to get their identity, and to ask them something simple like to describe the house (in this example) so the arriving cops will know they go to the right address. Now of course you can get a description of the house with Google Street Maps, but 911 dispatchers can solicit some information like what color car is currently parked outside or suchlike. They could also look up who occupies the house and make a phone call while cops are on the way.
Everyone knows swatting is a real thing that happens and that it's problematic, so why don't police departments have procedures in place which include that possibility? Who benefits from hyped-up police responses to false claims of criminal activity?
Yes, there's a middle ground here.
My daughter was swatted, but at the time she lived in a town where the cops weren't militarized goon squads. What happened was two uniformed cops politely knocked on her door, had a chat with her, and asked if they could come in and look around. She allowed them, they thanked her and the issue was resolved.
This is the way. Investigate, even a little, before deploying great force.
