HHOW DO I KNOW IF THE INFORMATION I HAVE GIVEN HAS LED TO A SUCCESS?
Each caller is given a special code number that is unique to that caller- rather like a PIN for a bank account. The caller can then use this code number every time they call to find out the status of the investigation into the information given. If the information leads to either a recovery of property/drugs or to an arrest then the caller is eligible for a reward.
Dial 311 - Don't Hide It, Tell It. If you have information about a crime.
