The location of the police stations seems influential. I know in Berkeley crimes without a firm location get geocoded to police HQ. Do you think that might be affecting these maps?

Interesting, thanks for the info. I think it hopefully should be OK for the currently supported cities. Lots of cities have 0,0 as the geo point for crimes without points, which we filter out. For others such as SF, it looks like the police HQ is in Mission Bay which doesn't seem to have a high crime rate for any category. This info would also hopefully be included in the dataset disclaimers, and we didn't see this in any of the datasets we use.

But thanks for the info, this is great to know for any potential future expansions. If you see any cases where this might be happening for the currently supported cities, please don't hesitate to get into contact with us :)

SF has several police districts and district stations - may be worth checking against those, too: https://www.sanfranciscopolice.org/your-sfpd/sfpd-stations/s...
