This is a group of ordinary people, in the shopping mall, in the street, in the noisy crowd, they also like us, have distant concerns, there are children who can not let go of their family. However, with police uniforms, they have the responsibility of not letting go. They may be covered in dust, they may not be good at talking, they may not have outstanding achievements, but they stand up again and again and draw an equal sign between "ordinary" and "great" with the cry of justice.
They tell us with practical actions that heroes will never go far, and heroes are around us.
