Yes, Richard, I hope so too. At the moment, this murderer is being instrumentalized in a very stupid way on German TV. Because he is obviously an anti-Islamist, he is being portrayed as doubly evil by the woke press. His proximity to the AFD is being used to portray the AFD (far-right party) as even worse than it already is. In my view, this is the wrong way to go about it, because it will only further enrage AFD supporters and turn them against democracy. The man is accused of having very bad intentions and the planning was obviously very precise. But in my eyes, the perpetrator is still completely mentally deranged. He should not be instrumentalized for any interest group, whether from the right or the left. That's not to say that I want to defend him. By no means and he should receive his severe punishment (it's best to shoot such offenders in the act, in my opinion). Nevertheless, I would assume schizophrenia or psychosis because apart from Hitler, Stalin and Putin, nobody is that evil without also being mentally disturbed.
BTW all Christmas markets in Germany have been very well secured since the attack on a Christmas market in Berlin in 2017. This Christmas market in East Germany was not!
