This is why it is so important for citizens to pay attention to the laws that are being passed by  our representatives. For decades we have happily gone along with laws being passed that weaken the ability for people to defend themselves in court. It's only in recent history that a person could be convicted of crimes without 'intent' being proven. It is the rich who can afford powerful attorneys with better argumentative skills who continue to have better representation than the 99% of us who cannot when we get into trouble.
