Civil disobedience – Withholding obligations, sit-ins, blockades, shop-ins, occupations, bannering, "camping", etc., are all specific activities which constitute the tactical form of civil disobedience. In some way, these activities directly or technically break the law. Usually given most attention by researchers, media, and authorities. Often conflated with violence and threats because of direct action and confrontational nature, but should serve as a distinct category of action (both in the context of tactical and strategic planning and in the control of activity).
Collective violence and threats – Collective violence such as pushing, shoving, hitting, punching, damaging property, throwing objects, verbal threats, etc., is usually committed by a relative few out of many protesters (even tens of thousands). It is rare in occurrence and rarely condoned by the public or onlookers (particularly the media). Usually met with equivalent or overwhelming force in response by authorities.
Protest march, a historically and geographically common form of nonviolent action by groups of people.
Picketing, a form of protest in which people congregate outside a place of work or location where an event is taking place. Often, this is done in an attempt to dissuade others from going in ("crossing the picket line"), but it can also be done to draw public attention to a cause.
Street protesters demonstrate in areas with high visibility, often employing handmade placards such as sandwich boards or picket signs in order to maximize exposure and interaction with the public.
Lockdowns and lock-ons are a way to stop movement of an object like a structure or tree, and to thwart the removal of actual protesters from the location. Users employ various chains, locks and even the sleeping dragon for impairment of those trying to remove them with a matrix of composted materials.
Die-ins are a form of protest where participants simulate being dead (with varying degrees of realism). In the simplest form of a die-in, protesters simply lie down on the ground and pretend to be dead, sometimes covering themselves with signs or banners. Much of the effectiveness depends on the posture of the protesters, for when not properly executed, the protest might look more like a "sleep-in". For added realism, simulated wounds are sometimes painted on the bodies, or bandages, usually made to appear bloody, are used.
