Corruption of any kind--political or law enforcement--always negatively affects communities by perpetuating crime. Certainly police corruption aids the criminal activity in many, poorer or minority communities as it gives the "go ahead" to the criminals as long as they provide the "kick-backs" to the police. Younger members of a community in which there is such corruption, then, perceive the police and the criminals as the same. Therefore, it is acceptable to engage in crime, and a profitable way of life.
Police corruption is wrong, no matter what social class you belong to. To add to this, I think that everyone would agree with this, no matter who we are talking about. Unfortunately, police corruption exists and it is unfortunate.
Many people in minority based communities, especially urban, already have a general feeling that law enforcement is there more for middle and higher class communities. In this way I feel that police corruption has a negative impact on the minority based communities.
It absolutely would have a negative effect, especially if the corruption involves officers of a different race than that of the community. Corruption in general undermines the confidence of community members and makes them rethink the trust they've put into authority figures, while the corrupt officers have already skewed interests. Corruption cannot be good for any member of the community.
I agree that police corruption will be looked down upon by nearly all social classes and communities, be they upscale or downtrodden. I believe all people can unite on this matter.
Corruption would tend to affect society as a whole by lowering trust in the police. This would make people feel less secure and less trusting of government. This, in turn, would weaken the bonds that hold society together.
I do not think this would work any differently in minority communities except that it would probably take less corruption to make them distrustful.
There is so much distrust already in minority underserved communities, regardless of the ethics of the police in those communities, that I find it difficult to imagine that evidence of police corruption would further impact those communities any more negatively. Perception is reality, and many minority citizens view the police as inherently corrupt.
Corruption in any public service including police, and in any community including minority based underserved community is bad for society.
A coorupt person including a corrupt policeman is likely to be more interested in personal profits and gains than in serving fairly any community. However a corrupt person is also more likely to let prejudices against a particular community come in way of doing his job fairly and honestly. This would definitely add to the woes of the minority.
