Informant-Initiated vs. Pre-Existing Crime: Prosecution Success Rates

SUMMARY

This dossier investigates the documented success rates of criminal prosecutions in cases where government informants played different roles: either proposing the crime (informant-initiated) or merely intercepting pre-existing criminal plans. While the use of informants by law enforcement is a long-standing practice for intelligence gathering and investigation, concerns about entrapment and the reliability of evidence arise, particularly when informants actively instigate criminal activity.

Existing public research, such as studies examining federal criminal court cases, provides general data on prosecution outcomes. However, a specific breakdown of conviction, plea, and acquittal rates directly correlating to the informant's role in initiating versus intercepting the crime remains an active area of inquiry. The provided sources discuss general aspects of criminal justice, federal court case examinations, and challenges in prosecuting certain crimes, but do not directly offer the requested comparative statistics.

STRONGEST CASE FOR

The government's use of informants, even those who initiate criminal activity, is a necessary law enforcement tool to uncover and disrupt difficult-to-detect crimes, such as terrorism or organized crime, where conventional investigative methods may fail. Prosecution success rates in such cases demonstrate the effectiveness of these tactics in securing convictions or plea bargains, thereby protecting public safety. Any lower success rate in informant-initiated cases might indicate proper judicial scrutiny of entrapment defenses, rather than a fundamental flaw in the tactic.

STRONGEST CASE AGAINST

When informants instigate crimes, it raises serious ethical and legal questions, particularly regarding entrapment, which can undermine the legitimacy of prosecutions and potentially lead to the conviction of individuals who would not have otherwise committed a crime. If conviction rates are significantly lower in informant-initiated cases, it suggests that juries and judges are wary of evidence derived from such methods, or that these cases are inherently weaker due to the lack of genuine criminal intent from the defendant. This also uses valuable public resources on 'crimes' that would not exist without state intervention.

OPEN QUESTIONS — PENDING LEADS

What specific studies, if any, have disaggregated federal prosecution success rates (conviction, plea, acquittal) based on whether an informant initiated the crime or merely reported on pre-existing plans?
Do Department of Justice or FBI internal reviews contain data on prosecution outcomes categorized by the informant's role in crime inception?
Are there academic or legal analyses that compare judicial outcomes for entrapment defenses in cases with informant-initiated crimes versus those where informants discovered existing plots?
Can publicly available federal court data be analyzed to identify cases where informants proposed the crime, and what were the conviction/plea/acquittal rates for these specific cases?
What are the definitions and criteria used by the FBI or DOJ to classify informants as 'instigators' versus 'observers' in internal operational guidelines?
