False Waivers Induce Fire Code Breach
Eric Espinoza managed a downtown hotel. An undercover fire marshal posing as a consultant repeatedly visited him over weeks and urged violations of occupancy limits and alarm systems for a cash convention. The marshal falsely assured Eric that temporary waivers existed and city officials secretly approved the plan. Eric initially refused on safety grounds but eventually directed staff to block exits after the continued pressure and assurances.
Reputation Evidence Tests Predisposition
Eva Espinosa was charged with bribery after accepting cash from an undercover agent who posed as a contractor. At trial she raised entrapment and testified about her clean record. The prosecution introduced prior similar acts to show she was already willing to accept improper payments before the agent's contact.

Common questions
Frequently Asked
4
What must a defendant prove to establish entrapment under the Model Penal Code?+
The defendant must show by a preponderance of the evidence that a law enforcement official or cooperating person induced the offense through knowingly false representations that the conduct was lawful or through methods creating a substantial risk that persons not ready to offend would commit the crime. The defense is tried to the court without a jury.
Supporting sources
Does supplying contraband alone establish entrapment under federal law?+
No. The mere provision of essential materials or contraband by a government agent does not by itself constitute entrapment. The key inquiry remains whether the defendant was predisposed to commit the offense before the government's initial contact.
Supporting sources
When is the entrapment defense unavailable even if inducement occurred?+
The defense is unavailable when the charged offense includes causing or threatening bodily injury to someone other than the person who perpetrated the entrapment.
Supporting sources
How does the objective approach to entrapment differ from the subjective approach?+
The objective approach focuses solely on whether the government's methods would likely induce a person not already ready to offend to commit the crime. The subjective approach additionally examines the defendant's predisposition before government contact.
