Entrapment in Post-9/11 Federal Terrorism Prosecutions (2001-Present)

SUMMARY

Since the September 11, 2001 attacks, the U.S. federal government has conducted numerous terrorism prosecutions, many of which have involved the use of confidential informants or undercover agents. Research indicates that allegations and indicators of entrapment are widespread in these cases, with one study suggesting a high prevalence. The effectiveness of entrapment as a legal defense in these prosecutions is reported to be low, with a small percentage of cases estimated to have thwarted genuine terrorist threats. Data on these prosecutions has been compiled into a database by researchers to analyze the patterns and outcomes.

STRONGEST CASE FOR

The pervasive use of confidential informants and undercover agents in post-9/11 terrorism cases suggests that the FBI and other agencies actively induce individuals to commit or plan acts of terror, rather than merely uncovering existing plots. The high number of cases with 'entrapment indicators' points to a pattern where federal agents may be manufacturing terrorism threats to secure convictions, as the defense is rarely successful in court. This approach allows the government to claim successful counter-terrorism efforts while potentially infringing on civil liberties and creating crimes that would not otherwise occur.

STRONGEST CASE AGAINST

Federal law enforcement agencies employ confidential informants and undercover agents as essential tools to infiltrate and disrupt genuine terrorist plots before they can materialize. The presence of 'entrapment indicators' does not automatically equate to actual entrapment, as these tactics are necessary to gather evidence against individuals already predisposed to committing violent acts. The low success rate of entrapment defenses demonstrates that courts generally find defendants had a pre-existing criminal intent, and law enforcement merely provided an opportunity, acting within legal boundaries to protect national security.
