I watched this a few weeks ago. It was pretty informative and made a lot of sense, but basically says you're pretty much fucked if they smell it or have suspicion, and there's no way to hide your stash from dogs.

Also, this guy didn't get busted or anything. He was one of the leaders of drug related arrests and realized a lot of the people he was arresting were normal, non violent people. I personally think its awesome that he was in the position he was in and yet questioned everything he was taught and discovered that marijuana was not as harmless as they made it out to be.

My favorite part was the part about profiling and what the drug indiction officers look for. Very good information.
