Why oh why Wednesday - Squad Cars

Why oh why?

So, you know those retired old unmarked police cars that you see on the streets that you know were once in service but have since been auctioned off?  

Well, my question of the week is, why oh why is it that you only see black people driving them?  I first noticed this and then began a thorough investigation into each one I witnessed and have yet to disprove my theory. 
So, naturally I turned to the one and only black person I really know, my Jamaican friend Tyrone, and his naturally clever response was, "so they knew what it felt like to sit in the front seat." 
So, there you have it.
