Open Street Map export -from Mapzen- for the city of Baltimore; lots of infrastructure data here!
These come with the repo:
- FIT data
- compiled by the Baltimore Police Department Force Investigation Team, 2015
- data are categorized by the type of incident officiers were responding to
- except for a short list of FIT investigations, there are no details about the nature of the use of force on the part of the officer(s) involved
- note that the Baltimore Free School has started an initiative to record use of force by BPD officers not released to the public
- Fatal Encounters
- this is a dataset about people killed in encounters with law enforcement officers.
- the author, D. Brian Burghart of the Reno News & Review, suspects that it is currently about 30% its eventual size
- coverage begins in the year 2000 and goes to the present
- BPD Arrests
- these are public arrest records released at data.baltimorecity.gov
- they come with this notice: "This data represents the top arrest charge of those processed at Baltimore's Central Booking & Intake Facility. This data does not contain those who have been processed through Juvenile Booking."
- Baltimore Urban Tree Canopy (UTC) assessment fine scale land-cover classification made for the US Forest Service, 2009
- data from UVM Spatial Analysis Lab
- US Census 2010
- Baltimore Riots, a Google MyMap initiated by @VinylFox and @Ryan_J_Smith
Note that these lists are absurdly far from comprehensive!

Consider using an easy web mapping platform like CartoDB. If you do spatial joins, or zonal statistics, and export a CSV from QGIS you can easy load it into ChartBuilder to make a pretty chart.

Map of Baltimore riot activity from afternoon of 4-27-2015 to morning of 4-28-2015.
Activity was manually pulled from police scanners, transcripts of police scanners, tweets (official and unofficial). Mapped points are by no means exhaustive.
