Ok, I understand your point.
I don't know how it is in the US but over here, the police force has the right to question you, to frisk you or to ask for your ID if they feel like you're a danger. Running away from the police is not illegal but refusing to stop when told so by them, is. What I mean is that the responsability of the chase is on the victim and the responsability of the victim's death is on the cop. Clearer, I don't put the death on the victim, only the chase. I don't know how one can see it otherwise.
For example, I was once taking photos of luxury houses for a project and the police (probably alerted by some neighbour) came and asked for my ID and why I was taking photos. I showed my ID and explained the reason I was doing this, which was for school. That took 1 minute of my time and bothered me a bit but at least after, I was free to go and take photos at will.
How would have they reacted if I fled the scene on my bike ? By letting me go ? Like "he's fleeing, no big deal" ?
If somebody steals my phone and thinking I got him, I question a dude and he runs away, how should I react ? Letting him go ? Like "he's fleeing, no big deal" ?
I'm sorry to say it but nowadays, if a cop asks me something, I obey, period. I record the convo (audio and/or video) if I can, but I do as s/he says. And you should also do that ABOVE ALL because you live in the US. Your cops got guns, breh and basically the license to kill. Mine only got tasers and/or flash balls or just batons sometimes. Even if you're in the right, you'd put your life in play for that ?
