This approach involves the police standing back, maintaining a watchful presence but allowing the protest to continue without intervention.
Often police will even assist or facilitate a march or rally by managing traffic like they would for a parade or other public event. Police may negotiate with third parties affected to simply let the protest happen.
At small actions, even ones that involve potentially unlawful actions, police may decide it is easier to stand by and watch than to intervene. This depends on the length of the protest, the level of disruption to others, police resources and the political climate surrounding the action.
It is often the case that this is easier than options below and will avoid escalating conflict. Accommodation recognises that police intervention can have a destabilising effect and lead to disorder at an otherwise peaceful protest.
Sometimes police will maintain a low-key visible presence but have a larger contingent of police or police horses out of sight nearby. It is useful to take note of the level of visible and hidden police presence as the situation and police tactics could change rapidly.
