I understand exactly what you are saying, however, there is always someone who has to do the so called "dirty/ugly jobs" in our society. Also, in this country the Law works on the basis that you are "presumed innocent" and as such, the prosecution has to prove otherwise. I don't envy the role of a defence lawyer ... it must be terribly difficult for them to have to keep quiet about what they know, but I do understand it. Many innocent people have ended up in jail for long periods of time, but now thanks to DNA and other modern technologies, they are proven innocent. Imaging their defence team, believing that the person is innocent, how they must feel when they loose their cases. I'm sure defence lawyers have a conscience and are not inhumane, but they have to abide by what the Law stipulates. It goes both ways.
