The police issued a statement on Twitter, this was covered extensively...I am thinking that you are the type of person who is resistent to evidence that counters your opinion that you have just stopped being able to process information, you just loop through your feelings. In addition, it has also leaked that the statement they issued was dialled down significantly and the original line was to blame Nowak for being stabbed...again, this is because their policing policy was to accept any accusations of racism in full.
If you just read stuff properly, you would know all this and wouldn't find yourself backed into a corner arguing against all forms of reality.
