It is a matter of perspectives.
Black peoples in US are often very rude and prone to crime.Considering lack of higher education and economical distress,it's pretty much explains itself.But so are the most poor and less educated whites in many parts of the US,though little less than the blacks in number.
I found most white peoples in US polite,helpful,pleasant.But I won't expect any less from an highly educated person.But when I say this I say the exact same words for many educated,economically solvent Blacks too.
Any way What I was trying to say is the socioeconomic matters should be considered.And I say that from my personal experience.
And to the OP,brother try reading the title of the thread,it gives racist impression enough.What were thinking when you were writing the title??Here in Germany,I met literally hundreds of people both highly educated and German-non German,Muslim and Jew and christian who thinks shooting of unarmed Blacks were indeed unethical and shows the deepest scar of the American Society.I hope you will understand.
