That would mean that the State is actually making some deep analysis. The level of analysis here is very very shallow: a set of registration numbers jotted down by a police officer on a parking lot 5 months before. The rest, which is already not much at all, is at best heavily biased dice throw, or as the author suggest simply planted evidence. No deep connection check ( like government monitoring database for activities like on reddit trees ), background analysis (why would a rich family start a home pot operation in the first place), no basic policing work ( electricity/water consumption, movement, contact with dealer, ...). Parent can say whatever he wants here. Visiting a fishing and hunting shop, or picking his friend at the gun range is all that is needed for the police.
