Understandably but that's often because of a feedback loop by their bad behavior. If those troubled neighborhoods collectively saw the cops as actually serving the community (rather than terrorizing it), they would likely be welcomed and safe.

Most of the resentment stems from how much crime is committed in these neighborhoods, which requires police presence, and how the penal system in the U.S. punishes rather than rehabilitating those found guilty.

Also, the lack of cooperation in poorer neighborhoods is largely due to respect for, or fear of, the criminals.

There's a lot more layers here - this 'shift' would require tons of slain officers, a lack of respect for the law, so on and so forth.

While I agree officers should do their best to serve the community, disarming them in dangerous areas isn't necessary to accomplish it.
