The goal is to first and foremost raise awareness about the issue of racist police brutality that has been endemic within our country since time immemorial, and to force a dialogue. In this regard, there has been a tremendous amount of success. Unless you're someone who is completely detached from all forms of media, it is likely that you've been made aware in some way of what's going on. That's hugely powerful in and of itself, and the sheer number of threads in PaRD, including your own thread, are testament to that very power. It has eclipsed virtually everything else going on, even the on-going global health pandemic, in terms of coverage. It has forced attention on an issue that has gone disregarded for too long, and now people who often describe themselves as "not political" are outraged, demanding change, and protesting.
Specifically, it has seen charges against officer Derek Chauvin, with the hopes of future charges for the other officers who stood idly by as Chauvin killed George Floyd. How likely would this have been the case if the murder of George Floyd wasn't recorded? Wasn't made viral? Wasn't resulting in everything we're seeing? It's very unlikely that anything would have happened and George Floyd merely another name added to the list of people officer Chauvin has killed in his career.
Historically, these protests have resulted in local police offices changing how they conduct not only their training, but also their work. We've seen increases in the use of bodycams, updates to police training, less acceptance for death while in custody or detainment, and a restructuring of how these incidences get investigated when they do happen.
