Ok, right... I got two questions mixed up.

1) Is it entrapment when the undercover agent makes a transaction to another person (somebody unrelated to the exchange) or Bitcoin-address which can not be identified?
Because there is no clear benefit how the person benefits. Would that be considered the same as if the undercover agent would give it for free or is it still a transaction because you requested that address.

2) Do you think undercover agents are willing to transfer money to (escrow) Bitcoin addresses in advance in order to catch the dealers? Wouldn't that greatly increase the cost of catching these guys?
