In Chandler, Arizona, the police will not act upon an anonymous tip. The caller has to reveal his identity in public records, thus exposing himself and his family to retaliation by the perp(s).
“The caller has to reveal his identity in public records, thus exposing himself and his family to retaliation by the perp(s).”
If you have a neighbor you do not like identify them as the caller. If they check the phone number just say you are visiting another house (your house).
Problem solved.
