When you report hate crime, you become part of the movement to stop it. No matter how small or trivial you think the incident might be, it is important to the whole community that it is acknowledged and reported.
Every report builds up a picture of what is really going on in your local area, showing patterns of behaviour against a certain group or by particular individuals.
The more that local agencies like the Police and Councils know, the better they can educate, inform and protect everyone in the area.
