@dang or other HN mods - can you help me understand why this post was so rapidly downranked? It's now on the 6th page... it's got to be the highest upvoted yet lowest ranked post submitted today. As far as I can tell there were no flags or anything. Am I missing something here?

Thanks! Yeah unfortunately with cities like SF nowhere is truly "safe to park" but hopefully this helps people avoid the major hotspots!
It's actually quite safe to park in SF with two exceptions: - With anything visible that might contain a valuable. Any devices in the trunk should be in Airplane Mode. If you're a tourist, don't park by a tourist trap. - Any model with an oft-stolen catalytic converter, esp. Prius. SF itself has higher-than-average tourist density, so it's a burgling destination too. But it's possible to park for decades and never ha…
This map makes me think of the New Inquiry's White Collar Crime map [1]. That project creates a strong image which for me disrupts the stereotype of what crime looks like and where we can find it. I realize it has a very different aim than safemap, but I frequently use it as an example of how the selection of data sources and its visualization is crucial in communicating a particular story. This communication already…

it’s not surprising if you’ve ever lived in that area
It is somewhat surprising actually. Presumably if there's an actual hotspot that police would be ever-present in the area until it dilutes out

I rather enjoy using either points directly (and for dense point maps use leaflet's cluster markers), or actual outlined areas (e.g. using DBSCAN). For a few examples I have put together

- Durham NC hotspots (leaflet), https://crimede-coder.com/graphs/DurhamHotspots
You need to divide crime counts by population density. Otherwise you're just plotting population density.

I dunno, I'd think car break-ins would at least be a very important statistic. My wife and I will be spending a day in the Fisherman's Wharf area, and the statistics on car break-ins has me concerned, though a co-worker who lives in the Bay told me that if I'm parked in a parking garage, it's less likely I'll be a victim, as it's harder to smash-and-grab-and-go when you have to deal with a parking gate.
if you’re really worried, don’t leave anything in your car and don’t lock it

Divided by population one of highest crime rate areas in the UK is Westminster because this are attracts a lot of tourists (some are targeted by pickpockets) but not much people live there (denominator is small). A better metric will be crime count divided by man-hours spent in the area per day. Such data unlikely exists in open access but mobile operators should be able to estimate it based on base station logs.
I don’t think there’s anything particularly wrong with it. What is it that you think is misleading from this metric?
