Terrorist attack in Halle: Investigators look for spectators of the livestream

The investigators of the Federal Criminal Investigation Office continue to look for three people who on the previous Wednesday, apparently idly on the Internet with how Balliet in front of the synagogue in Halle detonated several explosives and later shot two people. Using a helmet camera, the assassin had transmitted his murders live on the Internet portal "Twitch". The portal itself had first spoken of "about five" spectators after the attack.

The digital traces of the three wanted viewers led to SPIEGEL information about IP addresses in the US and Switzerland. Whether the people actually live there or whether they used obfuscation programs is still unclear.

CDU interior expert Schuster calls for dragnet 2.0

The investigations in the digital are apparently still at an early stage. Meanwhile, the interior expert of the Union faction in the Bundestag, Armin Schuster, already calls for the expansion of technical investigation measures in the network.

In the long term, one can not help but think about a strategic education on the Internet, says Schuster in the current issue of SPIEGEL. He is talking about "suspicious extremist content," the CDU politician explains his demand for a kind of dragnet 2.0.

Although more constitutional protectors are helpful, who are hidden in right-wing extremist forums. But only an additional "automated monitoring" would be effective. The use of so-called web crawlers, programs that scour the network for specific content, is also discussed in the security agencies. "But we are still in the beginning of the debate," says Schuster.

The chairman of the German Federal Police Detective Agency, Sebastian Fiedler, says in SPIEGEL: "Security authorities and policymakers must admit that we will not be able to handle these types of perpetrators on their own, and we are all called upon to prevent such crimes." However, there is a lack of prevention services for young men who showed such tendencies, says Fiedler. Only at the University of Giessen there is such a facility.

During his detention demonstration, the anti-Semitic assassin Stephan Balliet admitted that he had planned the crime since spring of this year. According to investigators, he described the anti-Christ massacre of Christchurch in New Zealand, in which 51 people died in March, as "a kind of initial spark" for his murder plans. According to the investigation, Balliet had begun with concrete preparations and also wrote the first part of a three-file self-assessment letter, which he published on the tattoo on the net.
