There are a few slight problems here.

The US justice system has always existed to benefit the rich and or majority of the time. I mean, really American history is filled with example where those in power ignored the less powerful below them and social unrest broke out. Every once in a while a rich person got blasted for the absolute unethical behavior they were engaged in.

Again, that is nothing new.

What is new is media and how people are subjected to this. There is no such thing as a local problem any longer. Anything at anytime can get shown to the entire world even if it's not real. So suddenly what would be an issue has thousands to millions of people talking about it. Unlike old media where they had some semblance of decorum, you get groups saying the most outrageous shit in an attempt to whip up crowds, it's even better when we find out later they've been paid off by foreign nationals and are acting like agents.
