As of Monday afternoon, neither Kurz nor his party had responded to the tweet. Vienna police responded on Twitter, saying that they had sent word of the tweet to the responsible authorities. Austrian media outlet Der Standard reported that regional counterterrorism and intelligence authorities are investigating the tweet.Österreicher/innen, abonniert TITANIC: https://t.co/MNWLQl2ta3 pic.twitter.com/Y2ouWWqKLV— TITANIC (@titanic) October 16, 2017Titanic retweeted the police’s response, commenting that the “Vienna department for time travel” had contacted them. The magazine’s head editor, Tim Wolff, told media publication Meedia that he had not been directly contacted by Austrian authorities.“We would like to acknowledge that in the case of this joke, there was a problematic crossing of boundaries — namely to Austria, where they are obviously not so nonchalant about their own Nazi past as we good, reformed Germans are,” Wolff said with irony. Austrian authorities are investigating a tweet on Monday by a German satirical magazine, which depicted crosshairs over conservative party leader Sebastian Kurz with the words: “Finally possible: Kill baby Hitler.”The tweet came one day after Kurz’s center-right People’s Party (ÖVP) emerged as the top party in Sunday’s parliamentary election, putting Kurz on course to become Austria’s chancellor.Nazi leader Adolf Hitler was born in Braunau am Inn, Austria near the German border. The tweet, which also says “time travel in Austria,” appears to be in reference to an age-old thought experiment: If you could go back in time, would you kill baby Hitler?
