I have yet to see a single example of how these tests are discriminatory and disadvantage minorities. SO...

This leads me to believe that those filing suit are either making an odd admission that the supposedly “affected minorities” really are incapable of passing a test that any human with enough brain to be a fireman or police officer ought to be able to pass with their eyes close... OR

They are racist towards themselves - wrongly believing that minorities are not smart enough to pass said tests.

It's right in the article-- "disparate impact". That means that minorities perform more poorly on the exam than whites, so that in itself proves it is racist.
