Original post by TrinculoThe quick answer, just to this bit is - you don't.
Firstly, I don't believe in grouping all people together like that as a "community". Just because someone is black, I don't believe that their code of beliefs or behaviours can be predicted or appealed to in such a way. There are people who are generally supportive of police, and there are people that are anti-police. The people that are anti-police, regardless of their intersectional characteristics, cannot be appealed to. There is nothing that police can do to improve the relationship, because the other side does not want to have a relationship under any circumstances. I'll give you a very simple example - Sadiq Khan. The Mayor of London is vehemently anti-police to the extent that more or less his entire non-political career was spent suing the Metropolitan Police, and his entire political career has been spent attacking and trying to damage or destroy the Metropolitan Police. Now, Sadiq Khan is not victimised by the Met, he isn't discriminated against by them, in fact he takes absurd liberties with the Met - he demands his own personal protection team (which no other Mayor has had and there has never been any reason to), he has gotten rid of a Chief Constable and continually suggests breaking the police force up. A person in a position of such extreme power - has no reason to fear the police - and yet is so deeply hating and distrustful - there is absolutely nothing that can be done to change their mind. Translate that to the hypothetical and somewhat ridiculous trope of the aspiring architect/footballer boy from the inner city council estate. They learn from quite a young age, especially on social media, how to challenge the police and exactly how far they can go and what they can say to "know their rights" which is nothing to do with their individual liberties, but more to do with being seen (as you say) as a "big man". Sometimes for no reason at all, a boy on the streets will say "Am I detained?" even though there was no suggestion that they would be - simply because they want to challenge authority. In such a situation, there is nothing that can be done. You cannot convince or educate a 12 year old that they can have a positive relationship with police - simply because it is not in their interest. They want to challenge the police, they want to try and get away with as much as they can - on what planet is trying to change that going to work?
As to the adults - I take you to the recent incident in Wales. Two idiots ran from police and later on killed themselves by crashing a high powered electric bike. Widespread disorder followed, mostly undertaken by adults. Was this because they were angry at police? Maybe, maybe not- but this doesn't happen when a nurse murders 8 babies, or a hospital negligently kills someone's grandmother - because people are not anti-NHS or anti-doctor in the same way. At the funeral of these boys, the parents played violent gangster hip hop about killing people and selling drugs. You cannot tell me that there is a narrative or education programme or initiative in the world that will improve relations between those people and police.
The best that police can do is try to keep the neutrals or pro-police people onside, and the only way to do that is by being effective at the job of preventing crime and arresting criminals. Unfortunately, in recent years police are seen as being less and less effective at that for a lot of reasons, and for purely political motivations, the focus has shifted to trying to appeal to tiny minority groups, and in so doing, alienated the majority.
In a sense- nobody is happy with policing, not even the police. Whose fault is it? Ultimately, government, media and social media - and the police for listening to them.
