Why focus only on blue-collar crimes and terrorists? Seems to me some of the worst damage to society is done through white collar crimes. Think: the S&L fiasco, Enron, the sub-prime mortgage mess, the thousands upon thousands of developments world-wide carried out because some government employee was bribed - how do you undo that damage? How do you undo the crimes of the current administration, including an unjustified war, trillion-dollar debt and untold environmental damage?
While I don't mean to triviliaze the damage caused by terrorists and sexual predators, if you are thinking large scale, theysimply don't compare to white collar crime.
You want to re-structure jurisprudence toward a preventative approach, fine, we can have that debate. But at least get the right target in your sights.
