Why?

Why didn't they just get a search warrant for the farm?

It's nice for the viewers pleasure to see all the drug addicts and the undercover cop becoming an addict...

It's safe to say the people who made this movie have got first hand experience with the addiction on some nice drugs and made good use of the animation to try to illustrate the effect they might have.

But with such an ending/story it's just not pleasurable to remember. I can't believe the 7.1 it got here, did the people who voted higher even see the ending?

Although it was less time consuming than watching 6 seasons of Lost, it's just as pointless.

If it was actually true that 20% of the population was using some substance that turns them into vegetables within months, you wouldn't think the government actually had to use ONE undercover agent that gets addicted and have to hope he'd be able to use one of his remaining braincells.

I bet that if 20% of the population was on a drug that has one clear legit beneficiary that is probably the main supplier too, they wouldn't really need a court order to burn that farm down.

Especially not in the USA.
