Observers have noted the militarizing of the policing of protests. Riot police are police who are organized, deployed, trained or equipped to confront crowds, protests or riots. Riot police may be regular police who act in the role of riot police in particular situations or they may be separate units organized within or in parallel to regular police forces. Riot police are used in a variety of different situations and for a variety of different purposes. They may be employed to control riots as their name suggests, to disperse or control crowds, to maintain public order or discourage criminality, or to protect people or property. In some cases, riot police may function as a tool of political repression by violently breaking up protests and suppressing dissent or civil disobedience.
