It should also be noted that the "Russian goverment attorney" wasn't actually part of the Russian government.
Plus, the "Crown prosecutor of Russia" isn't actually a thing. Look it up; there is no position with that name. The person they were referring to was Emin Agalarov, a singer and businessman, who met with his father, Aras.
So if someone tries to get drugs from a undercover cop, are they let go because the cop really isn't a drug dealer ?
