"New Zealand Police briefly informed Facebook of the livestream start and we quickly removed from the video and video Facebook and Instagram accounts," said Mia Garlick, Facebook's policy director for Australia and New Zealand.

What we know
Sometimes after the attacks, however, copies of the gloomy video continued on Facebook, YouTube and Twitter, raising new questions about the ability of companies to manage harmful content on their platforms.
Facebook is "getting rid of praise or support for crime and for the shooter or for the shooters once we know," Garlick said.
New Zealand police asked social media users to stop the purported shot footage and said they were trying to remove it.
This is the latest case of social media companies being caught by seafarers taking videos of their crimes by posting, and other users sharing the movies that have affected them. It has happened in the US, Thailand, Denmark and other countries. How quickly should it be expected to be removed?
"While Google, YouTube, Facebook and Twitter say that they are collaborating and acting in the interests of citizens to remove this content, they're not really about them ' let these videos come again constantly, "said Lucinda Creighton, a senior consultant at the Anti-extremism Project, an international policy organization.
Facebook does not seem to have artificial intelligence tools and human modifiers able to detect a live stream of the shot. The company says it has been informed by New Zealand police.
"The high-tech companies do not see this as a fundamental priority, breaking their hands, they say this is terrible," Creighton said. "But the thing they are not doing is preventing from revisiting."
John Battersby, a counter terrorist expert at Massey University of New Zealand, said terrorist attacks had been mitigating the country, partly because of his isolation. That changed social media.
"The other two people shot the shooting and his supporters have encouraged him, and most of them are not in New Zealand," he said. "Unfortunately when it's out and it's downloaded, it can still be (online)," he said.
The dissemination of video could inspire copies, said Steve Moore, CNN's law enforcement analyst, a special supervisory agent retired to the FBI.
"To speak to the public is this: Do you want help with terrorists? Because you make this video share with you," Moore said.
"Don't share the video or you are part of this," he said.
