large gathering of police officers wearing helmets and shields, standing shoulder-to-shoulder in a street. Beyond them, there is a crowd of people, some of whom are walking towards the police line. In the background, there are buildings and banners hanging overhead. There is also what appears to be some type of makeshift barrier constructed from debris in front of the police line. The scene suggests a potential confrontation or protest situation.
