They absolutely do, but either way, if the issues are systemic then surely you can find a more recent article rather than expecting us to discuss data from the Obama era.
I'm sure these numbers are publicly available and if you're claiming that situation changed in a positive direction then feel free to show that. Meanwhile, thinking that life is just a series of random events that don't have systemic causes is a pretty hilarious way to live.
Yeah it's not like there were any big events in the meantime. Certainly not two elections of very different presidents or a whole global pandemic. Certainly nothing crazy that could change the data in one way or the other
If anything these events led to even further militarization of police in US, certainly can't think of any meaningful police reforms that happened during this time.
