No, seriously? Is an unlocked door or open trunk "entrapment"? I'd say talking someone into the theft, or offering to split the goods with them if they would help, or offering them cash to assist would be entrapmnt, but an open car?
This is not entrapment.
Here in Colorado, the police will ticket you if you start your car on a cold morning and leave it running, un-occupied. They say it is an open invitation to car thieves.
So, it is a ticketable offense if a civilian does it...but it's not entrapment if a cop does it?
I always thought it was akin to ticketing provocotively dressed women for presenting an open invitation to rapists.
