These policemen are trying to catch criminal suspects who illegally buy and sell foreign exchange, and whoever is greedy will be arrested.
Legally speaking, the designer of the police trap does not constitute a crime, and the person caught by the trap is suspected of committing a crime.
Supplement: Any police entrapment or arrest must be approved by the leader. You don't need a team, you just need a team leader to decide.
It must have been approved before going back to action. Even if it was not approved at that time, it is ok to make up the approval afterwards.
