I agree with ummmm, FredPuli43 & others. I did not read Jake's link on the UK law, but USA law defines "entrapment" as 'police inducing the defendant to perform an illegal/ criminal act WHEN SAID DEFENDANT HAD EVERY INTENTION OF OBEYING THE LAW.'
Because I am not a thief, if I were to walk by a car, even if unlocked, with a laptop, a diamond ring, &or 1000 pounds/dollars in cash, I would not reach in & steal it. Indeed, I would want to lock the car doors but would not, lest I be accused of attempted theft by the owner or police walking by!
True entrapment would be if an undercover bobby were to hand a laptop to a waiter/barman saying, 'Hey mate, please watch this for me while I go to the loo!' & then the uniformed police walk in & announce that the laptop is stolen & try to charge the barman with receiving stolen property!
