I get that at some point murder becomes statistics, but I still feel the need to re-emphasize that this is murder. Not more folks getting the flu because there are more folks.
I agree that murder is horrible, but the article seems to try to sell that these murders are related to their activism, which is not something you can say just based on the absolute number. You need to have the ratio to compare to the last year and to the base rate in the general population to make a better statement. Without it, we can't be sure of the real cause and might try to fix this at the wrong place, leading to us to not prevent murders effectively - so yes, you need to get your statistics right, even when talking about horrible incidents.
