The paper this is from is verging to the extreme right. He grabbed her ass (which is not ok) and she stuck a knife in his heart (which is not ok) killing him. You're the one to judge. Or not. Or leave it to the judges.
I just checked a proper source. He groped her, she pulled a knife and the guy backed away. She then came after him and stabbed him. That's no longer self-defense. Totally reasonable that she's charged.
Edit: It's actually in the article posted here nvm
Udo Gehring, Kaiserslautern’s prosecutor, said in a statement that the incident occurred on June 29. “The stabbing was preceded by the 64-year-old sexually harassing the 20-year-old by grabbing her buttocks, [which led to] an exchange of words, and the 20-year-old opening a folding knife she was carrying and making stabbing movements in the direction of the 64-year-old, whereupon he backed away and the 20-year-old followed him,” he said.
“The 64-year-old then grabbed the 20-year-old’s arm, which she was using to wield the knife. The 20-year-old freed herself from this grip and stabbed once in the same movement,” he continued.
It's kind of amusing how all the sources for this community are complete crap. Zerohedge, breitbart, dailywire and dailymail are all as biased as can be and routinely use technically accurate but sensationalized language to manipulate their readers into being outraged or shocked. This headline, for instance - the guy did technically sexually assault her, but many readers will assume the SA was much worse.
