Riddle Me This

I had jury duty this morning. It was boring, and I didn't get picked for a jury. Anyway, as I sat with about 170 other people, a curious question popped into my head.

Where are all the black people?

There were some black people. Just not enough. Wayne county is about 50% black (Detroit is the biggest city in the county, which is 84% black), yet there wasn't more than 20 black people in that room- I counted - and I rounded up. There should have been upwards of 80 people of African-American descent in that room

So, where were they?

Jury of your peers, folks. Bedrock of our criminal justice system and all. If that's important to you.
