The only way to have a credible system of justice is to maintain the principle that everyone is entitled to a trial, and entitled to be represented.
Sometimes, a case looks really obvious.
Sometimes, it looks obvious to some, but not to others.
Sometimes, some people will tell you it's obvious, and you can't understand what they are on about.
You can't sort cases into different levels of obviousness, because that becomes too subjective.
So, you have to defend the principle that everybody ... absolutely everybody ... is entitled to have their case decided at trial.
Even when the outcome looks bleedin' obvious.
