crowd of people at night, possibly a demonstration or protest. In the center, someone dressed as an angel with large white wings and a gold headdress stands out. People in the crowd hold up their phones to record the scene. Some are holding signs, including one that reads "ARAB LIVES MATTER" and "STOP THE VIOLENCE!". Others are carrying black flags attached to wooden poles. The location appears to be an urban street lined with buildings. The atmosphere seems charged with emotion, as people are actively engaged in the event.
