that your intent, in addition to your outright statement about things "being better" 30 years later, was to suggest that because of social media, things are "better", and they are NOT.
With over a decade of photos and videos shot of egregious acts (including on youtube, which has been around about 10 years), where have things "improved"? 
You may have some police departments finally trying to institute more "community policing" - something that was actually put in place in various municipalities 20+ years ago under Clinton after the Rodney King riots (e.g., here in Philly, they started bike patrols to get the cops out of their cars and back on the beat). But even the "embarrassment" of being exposed hasn't been enough to change many departments - particularly when the cops are acquitted time and time again in very public fashion.
Even with cops being given dash cams and body cams that film some or all of their actions, many don't seem to give a damn what they do because why? The courts won't hold them accountable due to the level and type of evidence needed to show "intent" for criminal cases, where even something lesser like manslaughter, gets thrown out.
