mate there's countless witnesses saying the culprit attacked the police. What more do you want?
To let the investigation play out rather than taking sides immediately?
You're taking the police at their word and some witnesses accounts that you've probably read on twitter.
You don't know what happened, you don't know what led up to it.
People on here, and social media, have quickly jumped into believing the police were wrong or the police were right, without knowing what the hell actually happened.
There's also people taking the police side because of their dislike of Muslims.
