The underlying problem is that people aren't being taught right from wrong. Too many grow up in fatherless households, or in households with worthless fathers whom themselves were not taught properly as children.
And the government has exacerbated the problem by funding all these dysfunctional households which continue to produce dysfunctional offspring.
I don't think police training is the primary problem. I think too many criminals is the problem.
Also I think the lopsided representation of blacks in crime, especially young black males, is a great portion of why the police tend to focus on them.
The government isnt going to teach people right from wrong.
Every community wants murderers and thugs off the streets. Black and white.
Your assessment may be correct. But now you are getting into social engineering, which is not ever been successful.
