How political democracy responds to public dissent is a real challenge. The state is to prevent social disintegration; this is a major obligation of the state. On the other hand, the state must allow the public to voice their dissent towards how they are governed: in a perfect world, these 2 obligations are balanced in importance and power. Police presence is not questioned or challenged, but their tactics are frequently challenged. Police are deployed in events of public order crisis, they bring the law, communication, and force to events of public order issues. The police have various legal instruments to disperse crowds and protestors. Police want to be in control of events, under their terms and rules. The police can remove anyone from protest events for breaching the peace. Protest policing limits and ability is very broad. During protests, the police has a very broad criminal statutes for arresting and removing people.
