Why It Matters
California law enforcement agencies are increasingly deploying undercover officers posing as inmates to extract confessions and incriminating statements from suspects held in custody. The practice, known as a “Perkins operation,” has helped secure hundreds of murder convictions but is now drawing scrutiny from judges, legal scholars, and defense attorneys who argue the tactic is coercive and risks eliciting false confessions.
What Happened
In 2015, Jason Zapata, then 24 years old, was arrested in Riverside County on suspicion of firing a gun into the air. While held in a jail cell, two undercover law enforcement agents were placed with him, posing as gang members imprisoned for murder. One agent was over 6 feet tall and weighed 300 pounds; the other was covered in tattoos from head to foot. The agents threatened Zapata with violence, claiming they would administer a “calentada”—a beating or stabbing—to extract information.
Three months passed before Zapata discovered his cellmates were actually police officers. The operation exemplifies a law enforcement tactic now drawing renewed examination across California, particularly in counties like Riverside, which has become a hub for such undercover jailhouse work.
Analysis of cases in Los Angeles, San Diego, Riverside, and Santa Clara counties reveals the scope of these operations. In some instances, law enforcement has placed as many as five undercover agents in a single holding cell with one suspect. The cells are equipped with hidden recording devices to capture statements, and undercover operatives have been paid up to $3,000 per day for their work.
By the Numbers
24 — Zapata’s age at the time of his 2015 arrest
5 feet 9 inches — Zapata’s height; 180 pounds — his weight
6 feet — minimum height of one undercover agent; 300 pounds — that agent’s weight
3 months — time elapsed before Zapata learned his cellmates were undercover officers
$3,000 — maximum daily payment to undercover operatives in some operations
5 — maximum number of undercover agents placed in a single cell in documented cases
Zoom Out
Perkins operations have become a standard tool in California’s criminal justice apparatus, contributing to hundreds of murder convictions. The tactic mirrors interrogation methods used elsewhere but operates within the confined and psychologically vulnerable environment of a jail cell, where suspects have limited recourse and face the implicit threat of violence from those they believe are fellow inmates.
Riverside County has emerged as a particularly active jurisdiction for these operations, with local law enforcement regularly sharing tactical approaches at state conferences. The practice reflects a broader tension in American policing between conviction rates and due-process protections, particularly as the operations disproportionately affect Black and Latino defendants.
Legal and Ethical Challenges
Defense attorneys and legal scholars increasingly question whether Perkins operations cross constitutional lines. Michelle Luna Reynoso, a criminal defense attorney based in San Diego, framed the concern directly: “It’s psychological war. How is this not considered cruel and unusual punishment?”
Critics highlight several vulnerabilities in the tactic. Undercover agents often employ false evidence—claiming to possess facts about a suspect’s alleged crime they do not actually have—to provoke admissions. The inherent power imbalance, combined with the threat of physical harm from supposed gang members, creates conditions that defense advocates argue naturally produce false confessions, particularly among young, isolated, or psychologically vulnerable suspects.
What’s Next
Judicial and scholarly scrutiny of Perkins operations is likely to intensify as more cases come under review. Whether California will impose new restrictions on the practice—such as heightened judicial oversight, limits on the number of agents per cell, or explicit warnings to suspects—remains to be determined. The outcome will influence how other states approach similar tactics and may shape the broader debate over interrogation ethics in American law enforcement.
