"Give me six lines written by the most honorable of men, and I will find an excuse in them to hang him."

I would guess you haven't had to experience such an unfair situation personally as you still have that young/naive optimism about the world. If you ever find yourself entangled in some legal technicality, you will realize that that is a really bad idea.

On a similar note, never talk to the police, no matter how lawful you may think you are.
