I do like some more detail in trials, not just in what you use to defend yourself, but how you plan on defending yourself. Some ideas.
---Self-Defense: You are claiming that the police fired first, so you had to respond or be killed. This can work in defeating the more 'public charges' such as murder, because you are defending yourself, but it may not work with more 'private' crimes such as Hacking and Kidnapping.
---Violation of Privacy: You claim that the evidence against you is either manufractured or was aquirred through the violation of your privacy, and hence should be thrown out. This will work with more private crimes such as 'Hacking' where reasonable doubt may exist, but won't work with the crimes are out in the open, such as when you are seen committing murder. It also won't work when Privacy laws are already at their highest, to claim further violations of privacy is just stupidity.
---Liberal Anger: You admit the crimes were done, but that you did it because you were driven insane by Conservativism, and thought all Conservatives are evil and deserve to die. If granted the necessary treatment and palore, you would no longer commit these crimes (of course, you will need to stay in an asylum for a while, and lose all your juice in the process of being 'cured'). It may work effectively with Elite Liberal populations who might be sympatethic to your pleas for forgiveness...but repeated use of the Liberal Anger tactic becomes less effective and might sway people that prehaps the Liberal Crime Squad is just lying.
EDIT: In retrospect, an Elitle Liberal society would already throw you in a rehab program to rehablitie you, so what you would be arguing in L+ is that...er...You don't need their treatment, it might make the condition worse, you could do it yourself?
