Quick answer

A buy-bust operation is a form of entrapment employed by peace officers to catch a person in the act of committing a crime, commonly the illegal sale of dangerous drugs. It is a valid and legitimate law-enforcement technique, distinct from instigation: in a buy-bust, the criminal intent to sell drugs originates from the accused, and the officers merely pose as buyers to catch them in flagrante; whereas in instigation, the officers induce an otherwise innocent person to commit the crime, which leads to acquittal. Because the accused is caught in the act, the resulting arrest is a valid in flagrante delicto arrest, and the seizure of the drugs is lawful. To sustain a conviction for the illegal sale of dangerous drugs arising from a buy-bust, the prosecution must establish: the identity of the buyer and the seller, the object of the sale, and the consideration; and the delivery of the thing sold and the payment. The corpus delicti, the dangerous drug itself, must be presented and identified. This is where the chain of custody becomes decisive: the prosecution must prove an unbroken chain of custody over the seized drug, from the moment of seizure and marking, through the inventory and photograph in the presence of the required witnesses, the turnover to the investigating officer and the forensic chemist, and up to its presentation in court, so that the substance seized is proven to be the same substance presented in court. Failure to establish an unbroken chain of custody, or unexplained gaps and non-compliance without justifiable grounds, creates reasonable doubt and has led to many acquittals, even where a buy-bust occurred. So a buy-bust is a valid entrapment that catches a drug seller in the act, but a conviction still requires proof of the sale and, critically, an unbroken chain of custody over the seized drug.

A Valid Form of Entrapment

A buy-bust is a valid law-enforcement entrapment to catch a drug seller in the act. The criminal intent originates from the accused (unlike instigation, which leads to acquittal), so the in flagrante arrest and seizure are lawful.

Elements of the Sale

A conviction for illegal sale needs: the identity of buyer and seller, the object and consideration, and the delivery and payment. The drug (corpus delicti) must be presented and identified.

Chain of Custody Is Decisive

The prosecution must prove an unbroken chain of custody — from seizure and marking, through inventory/photograph with the required witnesses, to the lab and court — so the drug seized is the same presented in court. Broken chains cause acquittals, even after a valid buy-bust.

Frequently Asked Questions

What is a buy-bust operation? A form of entrapment used by peace officers to catch a person in the act of committing a crime, commonly the illegal sale of dangerous drugs, by posing as buyers. It is a valid law-enforcement technique.

What must be proven to convict for illegal sale of drugs? The identity of the buyer and seller, the object and consideration of the sale, and the delivery of the thing sold and the payment, plus the presentation and identification of the dangerous drug as the corpus delicti.

Why do buy-bust cases get dismissed despite a valid operation? Because of a broken chain of custody. If the prosecution cannot establish an unbroken chain over the seized drug, or there are unexplained gaps and non-compliance without justifiable grounds, reasonable doubt arises and the accused may be acquitted.
