When I have a client who is innocent, here’s my strategy:
Refuse to produce documents proving his innocence;
Refuse to have witnesses who can prove the innocence come forward and testify;
Refuse to testify under oath to prove innocence;
Insult the judges who will be deciding, while bribing the rest;
Write long, insulting letters accusing the prosecutor of random, made up crimes;
Whine about it constantly to anyone who will listen.
I mean, what more do they need? Clearly, a guilty person would not do all that.
