mapping police violence: data

I wanted to explore the data collected by Mapping Police Violence
Using Tabletop.js to get data from the public spreadsheet URL.

Unfortunately each month of data has a slightly different set of column headers and values. I've attempted to normalize all entries to have the same schema:

{
    "name": "Donald Lewis Matkins",
    "race": "Unknown race",
    "gender": "Male",
    "state": "MS",
    "unarmed": "Armed",
    "date": "2015-03-01T08:00:00.000Z",
    "source": "http://www.sunherald.com/2015/03/01/6097241_george-county-man-killed-in-standoff.html?rh=1"
  }
