Very cool (I love good data).
I’ve looked over the data briefly, and the one thing that strikes me is that any way you look at the data, arresting people for marijuana serves no useful purpose. In fact, some data graphs appear to have a reverse correlation.
The racial statistics are disturbing, though not particularly surprising.
