Question: If Mr. Orange had not been killed would have he had to face charges for shooting the woman in the car, despite being a cop on an infiltration job?
Chosen answer: There would definitely have been an investigation. But it was also self defence and /or a reflex action of being shot himself. Also he could claim that Mr. White shot her.
Forensics would prove him wrong if he attempted to implicate Mr. White for the shooting.
Answer: As an undercover cop, Mr. Orange shouldn't have even participated in trying to take the car with White, as undercover policemen are never allowed to commit criminal acts unless they are forced to under extenuating circumstances. In the real world, Orange would probably have revealed his true self to Mr. White and arrested him at that point if he chose to stick around.
