One result of the stereotype is that creates fear within the minds of people who have not interacted with black people. So when 20 something idiots are given guns and a police cruiser to "patrol" (another historically loaded word), they get very jittery when interacting with black people. Resulting in far too many unwarranted death during arrest.
The other result is the amount of evidence that is required to convict a black person vs a white person for the same crime, one can guess (and its true based on death penalty statistics), that one would require far too much evidence to convict a white person vs a black person.
An ominous possibility is that the 20 something cop may have joined the force to satisfy his homicidal needs, and in such a case that person would actively try to get instigate a black civilian to attack him and once he does, he will be executed. Since its a black person, there is little or no evidence needed to prove that it was police brutality. Blacks are thus easy targets for anyone who wants to satisfy the need to commit homicide.
The white psyche is also extremely "self-centered narcissist", they are like 2 year old kids. When colored people point out an event or a statistic as racism, a lot of white people just scoff. According to them, racism is over. Its not there because *they* don't see it, as if *they* are the experts of racism rather than the people who are really impacted by it. They dont get that they are never the victim of racism. They may have been a victim of bigotry but they have never been a victim of racism. They are just like a 2 year old closing her eyes and decides that she is hidden from the world because she cannot see anything. This self-centered behavior seeks to belittle another human being's feelings, which goes hand-in-hand with "othering".
All this is codified in Derrick Bell's "5 rules of racial standing":
http://www.mdcbowen.org/p2/rm/define/bellsRules.html
FIRST RULE
The law grants litigants standing to come into court based on their having sufficient personal interest and involvement in the issue to justify judicial congnizance. Black people (while they may be able to get into court) are denied such standing legitimacy in the world generally when they discuss their negative experiences with racism or even when they attempt to give a positive evaluation of another black person or of his work. No matter what their experience or expertise, blacks' statements involving race are deemed 'special pleading' and thus not entitled to serious consideration.
SECOND RULE
Not only are blacks' complaints discounted, but black victims of racism are less effective witnesses than are whites, who are members of the oppressor class. This phenomenon reflects a widespread assumption that blacks, unlike whites, cannot be objective on racial issues and will favor their own no matter what. This deep seated belief fuels a continuing effort - despite all manner of Supreme Court decisions intended to curb the practice - to keep black people off juries in cases involving race. Black judges hearing racial cases are eyed suspiciously and sometimes asked to recuse themselves in favor of a white judge - without those making the request even being aware of the paradox in their motions.
THIRD RULE
Few blacks avoid diminishment of racial standing, most of their statements abot racial condidtions being diluted and their recommendations of other blacks taken with a grain of salt. The ususal exception to this rule is the black person who publicly disparages or criticizes other blacks who are speaking or acting in ways that upset whites. Instantly, such statements are granted 'enhanced standing' even when the speaker has no special expertise or experience in the subject he or she is criticizing.
FOURTH RULE
When a black person or group makes a statement or takes an action that the white community or vocal components thereof deem "outrageous," the latter will actively recruit blacks willing to refute the statement or condemn the action. Blacks who respond to the call to condemnation will receive superstanding status. The blacks who refuse to be recruited will be interpreted as endorsing the statements and action and may suffer political or economic reprisals.
FIFTH RULE
True awareness requires an understanding of the Rules of Racial Standing. As an individuals understanding of these rules increases, there will be more and more instances where one can discern their workings. Using this knowledge, one gains the gift of prophesy about racism, its essence, its goals, even its remedies. The price of this knowledge is the frustration that follows recognition that no amount of public prophesy, no matter its accuracy, can either repeal the Rules of Racial Standing nor prevent their or prevent their operation.
- white culture sees you as non white and black culture sees you as white (Jesse Jackson actually said that Asians are non- minorities in a recent interview here in the bay area, said that only latinos and blacks are true minorities). I can tell you, as someone who spent part of my childhood in the midwest being called the "gook" and the "nigger indian" by my teachers 
in school, that, no, Asians are not the same as white - not treated the same. I have had my share of being targeted and beaten by police (especially when I lived in LA and was caught in a white neighborhood) extra patdowns at the airport, getting followed around in stores by security, etc. etc. The black/ white thing is a pretty myopic view of race relations in this country and not the only issue - I see that blacks are treated unfairly for sure - but it is always hard to try to wave a flag for someone who is oppressed when that person treats you the same as the other guy.
