If you ever need to report an incident to the police, you can use this handy online reporting system for non-emergency cases. Even if reporting an incident doesn't always result in an ideal outcome, it is important to report them as police services tabulate reported incidents every year and use this data in order to assign resources where they are deemed to be needed most.  If an incident is not reported, then they have no way of acting on it (short term or long term).
