Entrapment: A cop handing a kid a can of spray paint to a kid and telling them to spray a wall. When the kid does the cop arrests him for doing so.
Sting: A cop sits in a car across the street from a pawn shop that he believes will get robbed that night. When the criminal shows up to rob it and does so the cop arrests the thug.
Need to make it more clear.
The rest of the quiz is great
You don't use a hitch to connect a trailer to the vehicle - that's a tow bar & tow ball.
I'm from NZ and didn't find any definition of hitch to match the clue - is it slang in other countries for the equipment used to connect a trailer to the vehicle?
