A couple of good articles. The first one is "Beyond #BlackLivesMatter: police reform must be bolstered by legal action" by Matthew Segal. "Courts have shaped American policing by defanging the fourth amendment’s prohibition on 'unreasonable searches and seizures'. Because the term 'unreasonable' is unclear, courts have had to decide which police intrusions, beyond the blatantly arbitrary, go too far. And the US supreme court’s consistent answer has been that scarcely anything goes too far.
This local article argues similarly. "Post-Stockley: There’s an elephant in the room" by Mary Edwards Wertsch
