Good post - Far too many people self-incriminate because they don't know their rights.
For example, lets say a cop walks in on you extracting. You can:
(a) Admit to the cop you were wrong, you didn't know, I'm sorry, blah blah blah. This doesn't look so good when the prosecution brings up the fact that you admitted extraction to the cop. Chance of getting off - slim to none.
(b) Keep your god-damn mouth shut. Even in heavy examination - YOU KEEP YOUR MOUTH SHUT (respectfully). Few months later who knows, your brilliant defense attorney convinces the court you were making mimosa soap. Even if they don't believe it, don't you have a slight edge on getting the case dismissed?
Or,
(c) Be really smart and make soap at the same time as extracting AND keep your mouth shut. The line between making soap and extracting is so thin that no court is going to convict someone on a drug charge when there's credible evidence that you were actually making soap. As long as you keep your mouth shut and play the cards right, your attorney should have all they need to get you off.
