Kudos to granny for being so positive about it and acknowledging that the cops have to follow up on the calls they receive, but if some anonymous tipster can bring down a SWAT team on some grandma’s house without any kind of check being triggered, that might indicate that there are some problems about how these issues are being handled. Other people may get out of this with much worse than a funny story to tell when two dozen cops decide to visit their house at night.
