  1. Without a universal system and understanding of what constitutes a hate crime aswell as potential bias from those who report & collect the data (police officers) there are substantial issues in this dataset. I recall only recently seeing a similar issue in the UK with issues on the reporting of sexual assaults and rape cases aswell as the improper handling of them ( there is a good article on this issue by the Guardian).

  2. I would love to group the data by religion ethnicity and gender identity to see where most of the cases lie. As well as sorting them by county with differing colors representing the different forms of hate crimes.

  3. Coming from a background in cityplanning i am painfully aware of the bisections that were created by robert moses (a very famous city planner) which carved up New York into segregated section, not only by race but also by socioeconomic status. With that in mind i would love to explore the counties themselves and thier potential relationship to one another and whether or not there are hot spots due to proximity between predominantly black and white neighborhoods and counties.

  4. As a follow up to this tutorial i would like to urge my representatives to look into how data is being collected in my local PD. I would also like to see data relating to Maryland hate crimes and thier prevelance in each county and to be able to play around with that data aswell.
