If you agree that they are not innocent, why hesitate taking them to court. Clogging up courts is not a good reason not to investigate and prosecute. Otherwise the wise guy financial types would repeat the scheme again banking that the scale of their crime amongst them would hinder prosecution, thus they will laugh all the way to the bank again and leaving the nation holding the bag.
I'll explain this simply: I'm a root cause analysis guy. Who caused the problem? Politicians advancing their vision of a social agenda. That same social agenda designed to create a permanent voting block to keep them in power, doling out government goodies to the moochers of our society, at the expense of those of us who work and produce.
Simply stated, remove the root cause of the problem so it never happens again. We disagree on who the real target should be.
