Well, I think you have to look at these cases individually. The same thing you write here echos what is written by conservative commentators about poor African American communities in the US. Of course, such commentary conveniently excludes the way poverty and unemployment is structural to the US economy and that there are systematic forms of racism embedded in the US legal code. These empirical realities force communities of color to take part in extra-legal activities and the violence that comes along with those activities. All of a sudden, "normal" society - as you put it - looks like a society of oppressors and "these people" - as you put it - look more like the oppressed than a bunch of ne'er do wells.
