Undercover cops in New York are riding the subways with iPods on to entice robbery. Is that a form of entrapment? If not, why not?

Entrapment is fairly specifically defined in law… It happens when the police create a situation where someone commits a crime that they would not otherwise be inclined to commit.

Not at all.

Enticement is not Entrapment.

I told my 13-year-old daughter that she should never start a fight, but has my permission to end it. She got suspended for ending a fight that some other girl picked with her by hitting her then retreating. How do I handle the school’s response?

Government agents may not originate a criminal design, implant in an innocent person's mind the disposition to commit a criminal act, and then induce commission of the crime so that the Government may prosecute. Sorrells v. United States, 287 U. S. 435, 442. Jacobson was not simply offered the opportunity to order pornography, after which he promptly availed himself of that opportunity. He was the target of 26 months of repeated Government mailings and communications…

The most famous example of Entrapment is probably Jacobson v. United States, a case from the early 1990’s about child porn. In this case, the government repeatedly offered Jacobson illegal content, and provided a whole bunch of reasons why he should purchase it under the guise of free speech, etc.. When he eventually did (after two and a half years of basically being pestered about it), they arrested him.

From the circuit court ruling:

Can it be true that people know your name, not your story, they’ve heard what you’ve done, but not what you’ve been through, so take their opinions of you with a grain of salt?
