There were a lot of questions about whether Sacoolas had actually had diplomatic immunity, due to not being a diplomat and not having the paperwork a normal diplomat would have. Although perhaps it's to be expected that spies' paperwork would be irregular. There was also a claim that Sacoolas had some sort of secret diplomatic immunity under a secret treaty. Some reports claimed US spies had diplomatic immunity only while on the military base, while their families had immunity even while off base, implying Sacoolas would have immunity unless she was a CIA employee. Which she was at the time, according to some reports. Or was she merely a former CIA employee? Understandably, the CIA is not in the business of confirming such matters. I agree with you that there is nuance involved. I would say the precise nuance is irrelevant. Whether Sacoolas had immunity in theory is unimportant - only that she had immunity in practice.
