Obama Says Anti-Cop Rhetoric Can Hurt Black Lives Matter
If you view "them" (whichever them) as the enemy, they will treat you as the enemy.
If you view "them" as your friends and as members of your own community, you can help each other get rid of the bad elements that are poisoning the relationship.
Here is a tip: try turning any bit of anti-police rhetoric on its head: replacing "police" with "black people" and "blacks" with "police." If the black community would find the resulting statement offensive, then the rhetoric is not helpful, it is part of the problem.
eg: Police need to stop killing black people
Black people need to stop killing police
Police are racists who target the black community for being black
Blacks are racists who target white police for being white
We need to arrest all the bad apples on the police force and put them in jail
We need to arrest all the bad apples in the black community and put them in jail.
This is not to say any of the statements are untrue - they may or may not be, that is not the point - it is merely a test of whether the statements are helpful in building a better relationship between police and the black community.
If large numbers of the black community disrespect and stereotype police, particularly white police, meeting them with non-cooperation and fear, there can be no end to police stereotyping and fearing the black community. The only hope for a better relationship is for the black community (including Black Lives Matter) to work WITH police rather than against them. And vice versa: the police need to work WITH the black community, including BLM.
The police-BBC relationship in this case was just plain sick: the police and the BBC were both simply trying to boost their own public image at the expense of someone whose only crime was to be famous. Just as they did with Leon Brittan.
They particularly dislike anyone who will not give them more of other people's money.
