State Police Issues

I read in yesterday's Star Ledger that the NJ Stae Police have made a great effort to make the force more diversified. The problem they have had is that the African American recruits can't pass the written test, the women can't pass the physical, and the Latinos can't pass the background checks.
Now this makes me wonder about a few things.

First, are the tests biased? If so, how?

Second, whom of these minorities are we recruiting? Is it an open call? If so, then maybe we should target African American college graduates, or create a system where top high school kids can get a State Police scholarship.

I hope that the test is never skewed to make it easier for minorities. I want the best and the brightest, not the pretty good, in our State Police force.
