If you fix and then click on the link in my post it takes you to 8chan 's spreadsheet of arrests.  There is one for 2016 and one for 2017-8. At the bottom of the arrests columns are the totals. The first page of the spread sheet talks about length of time from arrests to sentencing.  He isn't very specific about what was happening under obama but Im imagining ppl were being convicted and then sent home to await sentencing and then never sentenced.
