With regards to the supposed unfairness of the justice system with a disproportionate effect on minorities, I leave this fact:
In 2010, the Fair Sentencing Act was passed to more equally handle the legal punishment of crack cocaine versus powder cocaine.
Crack cocaine is the cheaper and more easily accessible version to poorer people. Powder cocaine is the more expensive kind more likely to be used by wealthier people.
Prior to this act, a person in possession of only 5 grams of crack cocaine would receive a mandatory 5-year minimum sentencing, whereas a person possessing powder cocaine would have to have 100 grams to receive a similar punishment. A person with 10 grams of crack cocaine would receive 10 years of minimum sentencing; but it would take 1000 grams of powder to receive a similar punishment.
One of the effects of the War on Drugs was the disproportionate punishment of the poor and minorities, especially with regards to cocaine possession.
Now, I by no means support ending the War on Drugs, or think that legalizing drugs will make everything fine and dandy. But, I do think there are still things which more negatively affect minorities in our legal system, and it is right to discuss those things.
