Police intervention is society’s preferred method of maintaining law and order. As the cold weather sets in, we hear less and less about the Occupy Wall Street movements that swept the nation and the subsequent police response to it. Many observers, including the media, found the protest laudable and heavily criticized what they viewed as an overly aggressive response by the police. The police response to the protests raised some interesting questions regardless of where one lies on the political spectrum: When is police intervention required and how much force is appropriate?

By now, we’re all too familiar with the more infamous imagery to come out of the movement: That of the a police officer allegedly running over the leg of a National Lawyers Guild observer and of a UC Davis police officer pepper spraying a group of allegedly peaceful protesters. When these photos and videos went viral, the media generated a huge amount of publicity around the images. Amidst the anger and outrage sparked by the media frenzy, few in the public even noticed when these two incidents were discredited. In the NLG episode, there is evidence to suggest that the event was staged and the observer faked being run over by the police. In the pepper spray incident, a longer and perhaps more complete video suggests that the police reaction was not entirely unprovoked. The police were being surrounded on all sides by protesters demanding the release of two of their comrades. After the police gave numerous commands to clear a path, they finally resorted to pepper spray to clear a way through the throng and ensure their safe exit.

There are those who say that the police could have simply stepped over the students and avoided spraying them, which itself raises an interesting question. Should we require our police officers to subject themselves to these dangers? The job of a police officer is dangerous by definition, and a simple arrest can quickly turn into a more threatening situation. For example, after an NYPD officer attempted to arrest an OWS protester on New Year’s Eve, he was stabbed in the hand. Luckily the officer was treated immediately, hospitalized and released. However, incidents such as these underscore the dangers that that police face each and every day.

As a society, we have vested our security in the hands of the police and accordingly we should defer—and do defer to large extent—to their experience and on-the-scene judgments. Police are faced with many unpredictable situations. A seemingly routine police action can suddenly turn into a dangerous and life threatening situation. This is especially a concern in NYC, a city of eight million people and only around 35,000 police officers. It would be extremely difficult for the police to contain a riot if one were to erupt in a city of this size.

The Supreme Court has recognized the challenges that the police face and held that in determining whether the use of force is excessive in effectuating an arrest, courts should consider whether the use of force was objectively reasonable in “in light of the facts and circumstances confronting them, without regard to [the officers’] underlying intent or motivation.” The touchstone of the inquiry is reasonableness, requiring the courts to consider, inter alia, the threat of danger to the officer and society. Graham v. Connor, 490 U.S. 386 (1989).

We should not wait for a situation to develop before the police are allowed to act, we should instead defer to police judgment. If a decision is made that a particular protest or protestor is getting out of control, or starting to infringe on the rights of others, the police should not only be allowed but required to take whatever action is necessary to diffuse the situation or eliminate the threat to public safety.

The NYPD’s response to the OWS movement has been faulted for using certain aggressive tactics to control the protests. However, we should instead celebrate their commitment to maintaining law and order. Their hard work and dedication have ensured that the OWS movement did not spiral out of control while simultaneously protecting a city of eight million people. Even if some protestors were inadvertently injured, the officers should not be overly criticized for the actions they took. The NYPD officers made on-the-scene judgments, and it is not for us to judge the appropriateness of these actions by viewing them in hindsight.
