"What happened to Freddie Gray, from what I've been able to gather, is horrific and inexcusable. But in the end, riots only provide the supporters of the hardline, law-and-order agenda with extra ammunition."
That kinds of sound arguement seems to be encouraging more rioting - i mean if your claim is, they haven't done enough rioting to get what they want...
As i posted ages ago, you're all talking about this terrible rioting, which is a sympthon, not the root cause of the problem. There is very little to discuss relating to the riots, they will stop over time as anger burns out, or police/army action will become the larger violence and disperse them, forcing the anger to find other outlets.
But the underlying issues will not have changed either way.
