-Entrapment is a virtually impossible defense to make -out. You have to show that you weren't inclined to -commit the defense, but the cops basically made it -irresistable for you to do it. You see why this has to -be: otherwise all undercover drug buys and the like -would be entrapment.
While not completely clearcut, there is a big difference between a 40-year old guy trolling through teen chat rooms to initiate contact, versus an undercover cop posing as an underage girl and soliciting guys until one responds. The issue of entrapment should be who initiatied the proposed illegal transaction.
