incitement is a crime (see the wiki article)
and I think you mean entrapment
see the wiki article
https://en.wikipedia.org/wiki/Entrapment
"The main authority on entrapment in the United Kingdom is the decision of the House of Lords in R. v. Loosely; Attorney-General's Reference (n.3 of 2000). A grant of a stay is awarded if the conduct of the state was so seriously improper that the administration of justice was brought into disrepute."
NJ can give us chapter and verse on this
the wiki article presupposes that this is done by a policeman
and the paedo ones you are talking about is paedo grooming
These are gonna try to raise the defence of impossibility
- they cant be attempting to groom a fourteen year old because there wasnt one at the end of the ipad
I have no idea if such a degence will get up and run
