While there is a great deal of dispute over the content of the video showing the arrest of 23-year-old Occupy Wall Street activist Cecily McMillan Saturday night, the N.Y.P.D. has no doubt as to who was in the wrong. The Daily News, in an article about an investigation into online death threats made against the police on Twitter as well as comments in a UStream chat, reports that Ms. McMillan was "seen elbowing her arresting officer in the face" as she was being led out of Zuccotti Park.

The officer who arrested the activist was reportedly injured as well:

[Cecily McMillan] was treated at New York Downtown Hospital and released into police custody, cops said. She was charged with assault on a police officer.

Her arresting officer suffered a cut to the eye but refused medical attention, police said.

Social media reports from Occupy Wall Street supporters as well as members of the media indicate Ms. McMillan may face charges of aggravated assault and bail as high as $50,000, but the bail amount has not been confirmed.

The video published by the Observer here and subject to a great deal of parsing across the Internet as well as the comments attached to that post is below.

Update: A video of events surrounding Ms. McMillan's arrest was posted Sunday by WeAreChange. The events in question occur around 6:45 into the 14-minute video. This will probably raise more questions than it answers.

Cecily McMillan, an Occupy Wall Street activist once profiled in Rolling Stone, suffered a seizure Saturday night during protest action near Zuccotti Park. Many on-scene reported Ms. McMillan had trouble breathing after she was tackled and handcuffed by law enforcement.

A video uploaded to Youtube late Saturday night purports to show the attack. Two women can be heard commenting, "There's Cecily," then there is confusion as the police clearly perform a violent take-down on someone in the crowd.

According to Jeff Sharlet's November, 2011 article about the Occupy Movement, this may be Ms. McMillan's second violent encounter with police. She is an organizer for the Northeast region of youths involved in the Democratic Socialists of America, which Mr. Sharlet reports is "the largest socialist organization in the United States." Ms. McMillan, however, once led a more conventional life:

She's a former cheerleader; she used to want to be a politician. She says her studies and her work – she's also a nanny – prevent her from sleeping in the park. But she's not afraid to put her body on the line. She was arrested after she charged Wall Street three times, a "direct action" that even some veteran anarchists – militant and masked – considered wildly courageous, if foolish. A cop thought so, too, blasted her with pepper spray, knocked her down, stepped on her head and snarled at her, "Shut up. You get what you deserve, cunt bitch."

Reports from various sources over social media and live feeds on UStream indicate she had a seizure and has been taken to an emergency room, possibly with cracked ribs. Jeff Sharlet posted a link to the video on his Twitter feed and pointed out, "Camera's far off & u can hear body smack."

The video supposedly showing Ms. McMillan's arrest is below.

Update: Bucky Turco of AnimalNewYork has published a video of the same event from a different angle. It is no less confusing in showing what happened to Ms. McMillan:
