In general, people know what is fair and what is not... especially people on the jury.

Keep Miranda by:

1. forcing a criminal charge and jury trial when you are charged with anything;

2. get your attorney (or you yourself, if pro se) to explain that even though the judge knows what the law is and tells it to the jury, that the jury has the right and duty to make or change the law depending on how they judge you... guilty or not guilty;

3. that if they don't like the law as it is, change it through their verdict.
