The alternative solution is to issue DEA and state police with baggies of methamphetamine to distribute at crime scenes, so that they can still score a ‘win’ when the subject of the warrant has “managed to hide” / “never possessed” the sought-after drugs mentioned to be found in the search warrant.
Finding no physical evidence of drugs at the scene is really just showing how sophisticated the drug ring under investigation is, hiding the evidence is proof that they were tipped off to the raid.
There must be a mole in the police who informed the 80-year old in time for him to hide the evidence. So get IAS to investigate one of the do-gooder police - any cop who’s voiced concerns about the overly-militarised aspect of the police force, or perhaps a cop who has a medical marijuana licence (or has someone in his family who possesses one, or associates with other people who do) - failing that, pick a police officer whose kill-during-search score is below average for the force. Those kind of officers are likely the subversive elements who are trying to derail the war on drugs.
