No. Homicides have still raised by 15% in 2024. This is a graph of rate increase in homicides, not of homicides. It's the second derivative (see speed vs acceleration)
OK. Are both lines calculated with that same metric? If so it's still apples to apples. The legend states what you have pointed out. (no it doesn't I misremembered, my bad) BUT STIL, maybe an editor thought the headline was too long?
At the same time, derivatives are known to be noise amplifiers. Second derivative even more so.
I fear the author wanted to talk about apples, the measurements didn't agree, so kept taking derivatives until the graph agreed with their bias. Why else talk about change in change of apples?
As always, misinformation has been spread, tweet succesfull ✅️
