This was a 1 to 1 interview with a newspaper reporter and yet most of the media are accompanying this (politically unwise) remark, with photographs of her with a microphone in hand taken at rallies in the past, as if she was saying this while making a speech.
The situation on the ground in German cities and even villages is very bad, there is crime, fighting and hundreds of children have been abducted (god knows what will happen to them). Emotions are running high and the situation is being exacerbated by a helpless feeling among the general population that the press and most politicians are covering up the reality.
It isn't surprising that when asked what can be done to prevent immigrants from storming across borders and overpowering the police in a seemingly never-ending stream, that someone gives such an answer, qualified as it was by her saying it was not what she wanted to see, but it was within the law.
