He is right. America's Founders would be astounded to find that many of today's defense lawyers believe it to be their constitutional duty to help guilty persons avoid the consequences of their acts. Their actions are in direct opposition to the Founders' understanding of justice (meaning that each person is equal before the law and should receive that which is due him--no more, no less).
Alleged criminals are entitled to have their day in court, with competent counsel, to present facts which may show them to be innocent of the charges against them.
Those law schools, law professors, and lawyers who use the American justice system to do injustice to their fellow citizens are perverting the system and wreaking havoc on the society (witness the Avila "acquittal" which allowed a monster to prey upon the precious Samantha).
One could never wish it, but if such monsters preyed upon the children of defense attorneys, we might see a change in some attitudes.
Absolutely wrong. The Founders came from the same kind of adversarial legal system we have today, a system that predates the Constitution. It's likely the Founders would have found the lack of ethics among some lawyers abhorrent, but they came from an adversarial system and enshrined it in the Constitution because it is the best system invented so far.
