LOL you claim something doesn’t exist but you don’t even know it’s definition. The whole idea of institutional racism is that it is NOT the result of laws or overt policies.
The following statistic (disclaimer: I have not vetted the statistic I am just using it as an example of the type of data that would indicate institutional racism) is indicative of institutional racism.
Although approximately two-thirds of crack cocaine users are white or Hispanic, a large percentage of people convicted of possession of crack cocaine in federal courts in 1994 were black. In 1994, 84.5% of the defendants convicted of crack cocaine possession were black while 10.3% were white and 5.2% were Hispanic.
