I believe that it is highly probable both the police and the media know more details about the shooters other than "male."
Are you retracting your claim that the police and the media know the identity of the shooter?
Just because the witnesses/victims at the punk party refuse to cooperate with police doesn't mean other people will not. Even in the violent ****hole that is Minneapolis, people are going to pay attention to gunshots and where/who they came from. I'm confident that not everyone who was witness to the shooting are complete regressive retards that refuse to cooperate with police when they are investigating a murder-mass shooting because black lives matter. The chances of no one cooperating are extremely small, in my opinion.
Have you any evidence that anyone is not co-operating with the police?
Have you any evidence that there are people you describe as "complete regressive retards that refuse to cooperate with police when they are investigating a murder-mass shooting because black lives matter" who are not cooperating with the police?
Same with the media. If they are not asking more details about two murderers who are on the loose, they are negligent.
How do the media know who to ask about?
