I would love to see the dispatch log from that call.     6:38 PM Person calls about neighbors children playing in their own backyard.  Was informed that that is in fact the purpose of a backyard.    7:16 PM Person calls back about children playing outside.  Informed that as it is not after quiet hours and as they were not being excessively noisy there was nothing the police could do.    11:58 PM Person called back about children and filed noise complaint.  Officers sent to house and found out that the children had been put to bed hours ago.  Officers arrested the caller for abusing 911.
