“A state trooper had been positioned in the store parking lot to collect the license plate numbers of customers, compile them into a spreadsheet, then send the spreadsheets to local sheriff’s departments for further investigation. Yes, merely shopping at a gardening store could make you the target of a criminal drug investigation.
“More than half a year later, the Johnson County Sheriff’s Department began investigating the Hartes as part of ‘Operation Constant Gardener,’ basically a PR stunt in which the agency conducts multiple pot raids on April 20, or ‘4/20.’ On several occasions, the Sheriff’s Department sent deputies out to sort through the family’s garbage. (The police don’t need a warrant to sift through your trash.) The deputies repeatedly found ‘saturated plant material’ that they thought could possibly be marijuana. On two occasions, a drugtesting field kit inexplicably indicated the presence of THC, the active drug in marijuana. It was on the basis of those tests and Harte’s patronage of a gardening store that the police obtained the warrant for the SWAT raid.”
