Maybe people outside of Vancouver don't know what Grow Busters is really about. They get tipped off, go in and tear down the show and leave. They don't investigate, they don't press charges (mostly) as those things take alot of man hours and its very hard to make cases stand up in court as our judges don't care about grow ops. Grow busters is just cost of doing business.
Its a show for the public and more than that for the US who believes we're "soft" on drugs
