My 'trail of tears' as you so sourly put it and just must add that it's all for me to get my buzz on:

" According to the ACLU’s original analysis, marijuana arrests now account for over half of all drug arrests in the United States. Of the 8.2 million marijuana arrests between 2001 and 2010, 88% were for simply having marijuana. Nationwide, the arrest data revealed one consistent trend: significant racial bias. Despite roughly equal usage rates, Blacks are 3.73 times more likely than whites to be arrested for marijuana."

Comparing things that are incomprehensible over time is a time honored method of expression.
