Yes it is necessary but there are far better ways to fight it than to riot and destroy property and people's businesses (many of them were owned by blacks as well!). Rioting doesn't really do enough... and by now we all have become desensitized to rioting, violence and war because there's been so much in the last 50 years- do you see marked improvement? There's been some yes but not nearly enough still sadly.
Unfortunately I suspect even WITH all this rioting etc, the issues will still be ignored for years to come.
Plus with the media and current...."journalism" (I use the term loosely)...it is too one-sided...they focus way too heavily on things that will bring in money-- bad stuff..murder, accidents, corruption to the point where it LOOKS like it is 1,000% worse. It's still bad- that I agree with but the media is still cherry picking.
