Here is the rating of their bias:
The Sun - Media Bias/Fact Check
From Wikipedia:
In general, tabloid newspapers, such as The Sun, Daily Mirror, the Daily Mail (see also the February 2017 RFC discussing its validity), equivalent television shows, should be used with caution, especially if they are making sensational claims. The Daily Express and Sunday Express should be treated with even greater caution.

Which are the Best and Worst Newspapers in the UK?
The article provided by the OP said that there was no assumption being made about it being politically motivated other than from the victims political party, not the police. I never said that it wasn't politically motivated, the point of my post was to show that the OP is being a hypocrite and I confirmed it. You can claim that the German police believe its politically motivated but you'll need to provide a source for that, and even if it is true it doesn't matter because the OP made that judgement based on the article provided in which no such claim was made.
