All reports of narcotic activities are screened by the Detective Bureau which may lead to drug buys made by the police. These buys are the best evidence and must be made under carefully controlled conditions. During this period of the investigation, you may not see any evidence of police activity. Individuals found at the location who possess drugs will be arrested. The courts may release them on bail and they may return to the neighborhood while awaiting trial.
Dealers often move elsewhere or stop dealing after an arrest.
Don't assume one report is all that is needed. If criminal activity keeps on occurring, keep on reporting the activity. All citizens that are affected by the criminal activity are encouraged to report it to the police. You can report criminal activity anonymously but if you choose to leave your name and phone number, you can be assured that your name will not be released to anyone or listed in any report.
