I can share some anecdotes from various sources.
People have called the police for some rather bizarre and trivial reasons in the past. Here are a few examples:
Kids selling lemonade: There have been instances where young children running a lemonade stand on their street have been reported to the police for operating without a permit.
Grilling in public: Some individuals have called the police on others for grilling or barbecuing in public parks or designated picnic areas, even when it's allowed.
Noise complaints for harmless activities: Police have been called on occasions for noise complaints regarding someone playing music too loud, laughing too loudly, or even for children playing noisily in their own yard.
Overdue library books: Though uncommon, there have been instances of libraries involving law enforcement to recover overdue books or late fees.
Sharing garden produce: In some rare cases, people sharing excess produce from their home garden with neighbors have been reported as "suspicious" activity.
It's important to remember that these examples represent unusual and isolated incidents, and most calls to the police are made for legitimate and necessary reasons. However, it's also essential for everyone to use discretion and consider the appropriateness of involving law enforcement in non-emergency and trivial situations.
