To critics of police violence, the video – which showed Officer Daniel Pantaleo using a banned chokehold to arrest Mr. Garner – was proof enough of wrongdoing.

WITNESS’ Executive Director Yvette Alberdingk Thijm published an essay on The Huffington Post tackling the question of whether or not video can be effective in preventing and ending police violence. She writes:

Reversing the practice of vicious policing demands an urgent overhaul of the judicial system. That, surely, takes more than a shaky, citizen-shot video. But the collective strength of citizen video – the ability for so many of us to document and the growing volume of documentation – is in fact exactly the right tool to catalyze these much needed changes. The continual light shed on abuses will make a difference. But more needs to be done for that to become a reality.

She outlined several ways that judicial systems and technology providers can help ensure that verified video can be used effectively in cases involving police violence. She also urged activists and citizens to continue their use of video:

While it may feel counterintuitive in the wake of yet another jury who disregarded a clear-cut video, I urge you to join the band of “little sisters and brothers” armed with cameras, capturing videos collectively showing patters of systemic abuse. Facilitated by improved digital technology to share and organize, we have the power to ensure, as our nation’s prosecutor said, “fairness for all.”

Yvette was also a guest on CUNY TV’s “Independent Sources” to discuss this topic. She was joined by activist Jason del Aquila of the watchdog group El Grito del Sunset Park.

The issue comes on the heals of a recently uploaded video from Russia that went viral. In it, a 15-year-old boy is harassed for his alleged homosexuality. On the WITNESS blog, Madeleine wrote:

Where does a video like this fall in the spectrum of human rights video? It documents abuse, but simultaneously inflicts it. That leaves human rights activists in a tough place. The same video that was originally circulated by Russian neo-Nazi sites is now being circulated by LGBT activists and news outlets worldwide. It has been uploaded to a half dozen YouTube channels, and translated into various languages. BuzzFeed, Gawker, and the Huffington Post have embedded the video in articles discussing the alarming rise of homophobic violence in Russia, just weeks after a new law criminalizes homosexuality.
