Speading terror online - moving from Twitch to Telegram

A shooting outside a synagogue in Germany yesterday was livestreamed on the Amazon-owned streaming service Twitch - a service used more than Facebook and YouTube for live streams. While Twitch said only five people tuned-in to watch the 35 minute stream in which the shooter killed two people, more-than 2000 watched a recording of the attack before it was removed. However, much like copies of the video of the Christchurch terror attacks, the Halle shooting is still available to watch in the not-so-far reaches of the internet.
