Will the Protests Help or Hurt the Racial Justice Cause?

Been engaged in a long discussion on Facebook with various members of younger generation who basically excuse all the violence over George Floyds death for various historical and emotional reasons.  I tried to make the point if they want to make progress on racial justice they have to distinguish between non-violent protest and violent protest.  Didn't feel like I made much progress so decided to do some research.

Since the 2014 events in Ferguson Missouri seemed to offer a recent similar sequence of events, I decided to see what happened in the 2016 Presidential election.  Interestingly, in an election that saw very low voter turnout in many states, in Missouri the turnout was unusually high, around 70%.

Then the question becomes who did the Ferguson events motivate to vote.

In the 2016 election in Missouri Hillary Clinton got the lowest vote percentage (just under 38%) for a Democrat since 1972.   Donald Trump got 56.4%.

It seems to me to suggest that the outrage at the violence sent more people to the polls than outrage at the original shooting.  

Be happy if someone can find some other statistics to explain this result.
