>With respect, I do not see why FBI crime statistics are considered racist. It is because it is a part of the US government?
Because this data requires serious, responsible and honest engagement, and it's tempting to use it to confirm biases.
Allow me to make a parallelism stepping aside from controversial topics. Imagine we had graphs of discovered vulnerabilities in closed source and open source software. It wouldn't surprise me if the amount of vulnerabilities discovered in open source software was way higher than those of closed source software. At first glance this may paint a terrible picture of open source, yet, if you actually engage with the subject, you would find out that the reason as to why this happens is that those vulnerabilities are found out, while they stay hidden in closed source. Yet anyone not willing to dig in that deep could point out and claim "See? Open software is terrible!"
In the same way, you can look at crime statistics by race and claim that black people in the US are terrible. This requires ignoring socioeconomic status and a whole lot of other factors, but it's really easy to ignore those and it's really easy to just point at a graph.
The data is not the problem. The way people engage with the data might very well be, this is a complex and delicate matter and it is my hope it can be dealt with in the way it deserves.
...Not that it has to be dealt with here, really, the website is pretty damn nice.
