And then I clicked the link and... 8ft? That's what, just over 2 meters? Who wants and desires to be within a NBA player's distance of a police interaction anyway? At that point you're not observer or recorder you're a participant. I find the title very very very misleading.
I believe police interactions should be recorded. I believe we should be free to record them. I believe they should be held to higher standard as the powers they get and their propensity to abuse them are huge. But if you're inside 8ft it feels you're just interfering.
Maybe there are angles I have not considered...
