This is the text (if you need help).
People are angry. A video of the killings in Christchurch is still on social media. A terrorist killed 50 people at two mosques. He put a live-stream on Facebook. People say social media did stop the video spreading. They asked people to stop sharing it. One said: "That is what the terrorist wanted."
Facebook said it quickly removed the video and the shooter's Facebook and Instagram accounts. YouTube said it removes videos when people tell them to. The UK said sites must do more to stop the spread of "sick material". It said social media sites must not "do the terrorists' work for them" and must not spread their ideas.
Back to the Christchurch lesson.
