YOU CAN’T MAKE THIS SHIT UP: Operation Constant Gardener

Filed Under: Drug War, Built for Television

Seven deputies entered a Kansas family’s home and searched it for more than two hours. What sent them there was stranger than anything they found.

It was a chilly April morning in Leawood, Kansas, an affluent suburb of Kansas City, when seven Johnson County sheriff’s deputies converged on a family home.

According to the 2017 appellate record, Robert Harte heard shouting and heavy pounding at the front door just before 7:30 a.m. No one expects that sound at breakfast. When he opened the door, the deputies surged inside.

They had come looking for something they believed was growing there.

The officers wore black tactical clothing and bulletproof vests. They carried firearms and a battering ram. The operation had not been classified as a high-risk entry, and police had no information suggesting that anyone inside was violent.

Robert ended up shirtless and facedown on the floor with an armed officer standing over him. His wife, Adlynn, ran downstairs after hearing screaming and pounding hard enough to rattle the walls. Their 13-year-old son and kindergarten-age daughter were both home.

Deputies ordered the family to sit against a wall before moving them to the living room couch. An armed officer watched them while the others searched the house. A neighbor later said she asked a deputy whether she could take the children to school. According to her affidavit, the deputy refused.

Although the family was not under arrest, the Hartes said police would not permit them to leave, an account the deputies later disputed.

Nothing about Robert and Adlynn suggested that a tactical team would arrive at their home. Both had worked for the CIA and held high-level security clearances. Adlynn was an attorney and a graduate of the Leawood Citizens Police Academy. Neither had a criminal record beyond a traffic violation.

Police knew almost none of that because they had barely investigated the people whose home they planned to enter.

The road to the Harte residence began eight months earlier, when Robert took his children to the Green Circle Garden Center and bought a small bag of supplies.

A Missouri State Highway Patrol sergeant named Jim Wingo was watching the store from his vehicle. He spent hours recording customers’ descriptions, license plate numbers, and purchases as part of what he called a pet project.

Robert visited the store once, and Wingo entered him into a spreadsheet.

Over the following months, no officer saw Robert return to the store, and police conducted no meaningful surveillance of his home. They did not check utility records or look for the structural changes that might have supported their suspicions.

Robert remained on the list.

By February 2012, Johnson County officers wanted another coordinated enforcement operation, with both the date and publicity strategy already chosen.

Wingo warned that he did not have enough new names to justify a full-scale operation, but Johnson County Sergeant Thomas Reddin intended to “at least make a day of it.”

Four weeks before the raids, the sheriff’s office began planning a press conference to announce success, putting a publicity deadline in place before investigators had grounds to enter the targeted homes.

Robert’s single shopping trip was not enough to secure a warrant. Deputies needed something more.

They found it in the family’s garbage.

On April 3, two deputies pulled the Hartes’ trash and found wet green vegetation mixed with ordinary kitchen waste. They decided it was not suspicious and threw it away.

The officers returned one week later and found similar material. This time, with the planned operation approaching, they treated it as evidence. Deputy Burns reported that a field test was positive for THC. The reported result moved the investigation closer to a warrant, but deputies still needed a second positive trash pull.

No photograph documented either the vegetation or the test result. When deputies returned on April 17, they reported a second positive result without photographing that test either.

The kit recorded only a preliminary chemical reaction and could not identify the substance conclusively. Its instructions directed police to send suspected material to a qualified laboratory for definitive analysis.

In his separate appellate opinion, Judge Carlos Lucero cited a study reporting a 70 percent false-positive rate for the kit. It had reacted to ordinary kitchen herbs, newspaper, and even air. The field test could point investigators toward more testing, but it could not tell them what they had pulled from the Hartes’ garbage.

Although the affidavit called the field result presumptive, it left out the kitchen-trash context and the lack of marijuana odor. It also omitted the difficulty identifying the material and the absence of laboratory confirmation. The Hartes later argued that those details would have changed the probable-cause assessment. Judge Gregory Phillips disagreed, concluding that the two reported field results still supported arguable probable cause. Phillips also noted that Kansas law allowed the approved field test to establish probable cause at a preliminary hearing. His analysis addressed whether officers reasonably relied on two positive reactions when seeking the warrant. It did not make those reactions conclusive. The disagreement did not make the omitted facts disappear.

Deputies never sent the samples to a laboratory before using the reported results and Robert’s eight-month-old shopping trip to obtain a warrant.

Three days later, seven armed officers entered the Harte home.

Within the first 15 to 20 minutes, they located the small indoor garden. It was visible through a front basement window and contained none of what had brought them there.

They kept searching.

Deputies opened drawers, looked under beds, and worked through the family’s belongings. After approximately 90 minutes, two officers claimed they could smell what they had failed to find. A detection dog was brought through the house. It did not alert.

The search continued for about two and a half hours. By then, deputies had already found the visible garden and learned that it did not contain the crop described in the warrant application. The discovery undercut the grow theory, but deputies shifted toward searching for evidence of personal use. The dog gave them nothing new, and its handler did not smell marijuana either. The family remained under armed guard while the search continued.

Before leaving empty-handed, deputies strongly suggested that the Hartes have their 13-year-old son tested for drug use. They had found no evidence that he had used anything illegal.

News from the house reached the sheriff’s office. Reddin initially accused the deputy reporting the empty search of lying, then sent an email to a lieutenant:

“SON-OF-A-BITCH!!!”

The reply was even shorter:

“Nothing?????????????????????????”

The sheriff tried to cancel the press conference, but notices had already gone out. It proceeded with prerecorded footage showing Sheriff Frank Denning near plants portrayed as having been seized during the raids. Officers had confiscated no live plants that day.

The coverage told the public that officers had seized contraband across Johnson County. It said nothing about the family held under armed guard while police searched an innocent home.

The Hartes fought for the records and filed suit. A federal judge dismissed the case in 2015. The Tenth Circuit revived several claims in 2017, but its three judges issued separate opinions with different reasoning. On remand, the district court allowed one federal claim to reach the jury. Jurors found that the Hartes had not proved the deputies lied about the field tests and that probable cause did not dissipate during the search.

The Hartes appealed again. In the official 2019 opinion, the Tenth Circuit did not overturn those findings. It reinstated separate claims concerning whether officers properly executed the warrant, exceeded its scope, and prolonged the family’s detention. Another trial was approaching when the parties settled.

In that separate 2017 opinion, Lucero called the operation the product of “junk science, an incompetent investigation, and a publicity stunt.”

The selected date was April 20, 2012. Police chose 4/20 because of its connection to cannabis culture. The operation was called Operation Constant Gardener. Emails surrounding the operation said the raids should make 4/20 “something to fear rather than something to celebrate.”

Emails after the 2011 operation floated T-shirts and a telethon-style billboard featuring a marijuana plant that would fill as seizures accumulated. Officials built the 4/20 operation as a show before investigators had the warrants.

The plant deputies expected to find inside the Hartes’ home was marijuana.

The plants Robert was actually growing with his son were tomatoes and other vegetables for an educational project.

The mistake was not even new. Operation Constant Gardener had targeted at least one other home containing nothing but tomato plants during the previous year’s raids. According to the appellate opinion, that failure became a running joke among the participating agencies. It did not stop them from building another operation from the same garden-store surveillance.

The material taken from the family’s garbage was not marijuana either. It was the wet remains of Adlynn’s loose-leaf Teavana tea.

Four months after the raid, the county crime lab examined the two retained samples. Its use of the same field kit produced two more false positives, but further analysis detected caffeine. A technician said the leaves resembled neither marijuana leaves nor stems, whether viewed with the naked eye or under a microscope. The crime lab later concluded that officers had used the wrong field kit for marijuana and recommended laboratory confirmation of suspected evidence.

The raid began a legal ordeal that lasted eight years. In 2020, the parties reached a $150,000 settlement.

One garden-store visit. Two presumptive test results. Seven armed deputies. Two frightened children. Eight years before settlement.

All because police could not tell marijuana from a cup of tea.
