Entirely and completely wrong. Understanding why things happen do not give those things justification.
> Now, if you're like me, rioting is not a solution for anything. It doesn't solve any problem, it doesn't bring the kind of attention that can solve problems. Rioting is simply a temper tantrum, and I refuse to give power to people having tantrums. Period
I'm not saying you should. I'm saying it helps more to understand why the riots occurred in the first place in order to prevent them from happening again. Not always, but usually, riots are not isolated events, but are the results of an accumulation of issues and problems. Yes, people are angry, and that anger led them to riot. So understanding why they were angry in the first place is a good thing.
