There's a slight misunderstanding of this theme on poverty.
Really I'm the same as you when the chips are down and I might unexpectedly have to defend myself or family from violent criminals. Just like yourself, I'd hit out first and ask questions later. Naturally you have to put yourself and a potential victim first.
But having embraced that initial reality, I believe politicians and sociologists, at the very least, need to consider the idea that crime is a social problem linked to a number of factors. I mean, I agree with Schwarzennegger when he pushes the line that sports can play a positive role in keeping people on the straight and narrow, as well as employment and opportunity, social programs and investment.
Let's face it, the reality for many people is life in a squalid flat in a run-down area with parents who could be into drugs or even alcoholics. Such people have never experienced a stable family environment. As a result, they wind up joining some street gang or other and, before you know it, they're behind bars.
In the worst case scenario, such an individual then finds himself under the jurisdiction of one of these ingenious sheriffs, we've been discussing, who decides that maybe parading the inmates publically in pink pants as part of a chain gang is just the ticket to bring about a change in atttitude. Usually the public applauds that kind of policy! It certainly gratifies the mainstream desire for revenge, but I don't think it does any long term good.
I agree with you that some crime cannot be excused so easily. Rape, for example, destroys the victim's life and you can't simply dismiss these actions as not being linked to personal responsibility. I think I'm talking more about gangland culture, street crime, theft and anti social behaviour.
You may know that police officers in Brazil used to simply accept the idea that street kids were a lost cause as they came from such deprived areas it was considered inevitable they'd fall into gangland culture. So, police simply did away with many of the kids and they went missing. However, liberals don't support policies that "do away" with potential gang members. Liberals recommend social funding for recreational programs, encourage sports, education and try to look into the root causes of crime.
