What you can't reasonably expect is that people who equate the word "justice" with the act of looting will somehow give a sh*t about the facts.
Not defending looting here, but the reason there's looting is because there's no expectation of justice. There are certainly more effective ways of handling the lack of an expectation of justice than looting; not arguing that. But if you bring in enough troops to stop the looting, the lack of faith in the government's version of justice will remain, and it will come out in some other--probably more destructive--way.
I suspect that one of the biggest reasons those folks are rioting and looting is because they don't have rifles or the training to use them from concealment. If they did, things would look a bit different. When a white community full of military veterans loses as much faith in government justice as the black community in Ferguson has, you'll see what I mean.
