step 1: be smart...there is always a way to get even but often the best way to do so is to let some time pass...hit the fucker when he thinks you've forgotten or given up.

step 2: be quiet...don't tell ANYONE what you're going to do or when you're going to do it. the only way you can make SURE no one will mess this up for you is if no one knows, sorry to say in today's world the only one you can trust is yourself.

step 3: be thorough, do your homework...come up with a plan and then cover all of your bases (as dumb as it sounds watch some court tv...the best way to learn the right way is to learn how someone else got caught and what type of evidence the cops look for and how and where they collect it)

just a few suggestions but they worked for me...some bitch ripped off approx 5K worth of my shit (already harvested, cured and bagged) 3 months later she was REALLY sorry.

P.S. make sure you have a GOOD lawyer in the background just in case...even the best of plans can go awry and legal back up is always good, expensive, but definately worth it unless you like jail.
