Indeed.
I'll be honest in saying that I do think the so called "lefty lawyers" are usually defending people most don't like (e.g. foreign criminals), but I also hate the government's characterisation of the lawyers themselves. Like freedom of speech, people have a right to a defence.
In fact, part of having a strong legal system is the fact that it optimises for false negatives. Better to let 100 criminals go free than one person unjustly imprisoned.
