What a conspiracy world you live in.
You know 100 years ago, there was far more racism, blacks had real hardship, were far poorer, and lacked civil rights - they had all the reasons YOU and other lefties pretend MUST lead to a life of crime and would have been convicted much more then.
Yet the prison population for blacks was actually quite low then.
The facts are that CRIME started really booming in the mid-60's, the great Liberal revolution times, especially in the Liberal Democrat run inner cities where blacks make up a higher percentage of the people. People were told at this point (by Liberal intellectuals and political leaders), that the system was to blame, or society, or the white man or poverty. That combined with social welfare programs like Medicaid, expansion of welfare, the Food Stamp Act, meant that people not only could blame others for their irresponsibility but they were largely not responsible for providing for themselves.
It is that attitude and that lack of consequences for their actions (ie: act bad lose your job, but not your welfare check) that lead to such a giant spike in crime as the stats clearly bear out:

And you'll also note that the crime rate decreased in the 90's when Republicans got tough on crime and started eliminating welfare.
A lot of immigrants come here poor as hell, from far worse backgrounds (some from black nations), but they are not in jails, not because some white racists love them and keep them out of there, but because they simply don't commit crimes. They have not been tainted by the poisonous message of Liberalism, that it is ok to commit crime because you are poor or because you are black or because society doesn't do enough for you.
The war on drugs is just as wrong as any government war like the war on poverty started by Dems and still the nations longest ongoing war, but whites are incarcerated from that too. It is hardly a black thing, blackassdolt.
