Yep, only police are allowed to engage in entrapment without suffering a penalty.
It wasn't the entrapment, it was the murder that happened along with it.
Police doing entrapment that resulted in the death of the subject would simply be self defense or at worst an accident. If there was anything wrong with police engaging in entrapment they would be arrested for kidnapping after it was determined that was what happened.
"My message to my troops is if you see anybody carrying a gun on the streets of Milwaukee, we'll put them on the ground, take the gun away and then decide whether you have a right to carry it." - Milwaukee Police Chief Ed Flynn
