Except we're not, actually, talking about a life here, PC Smith came from the building. So either she left a tense situation upon hearing that a photographer had a shot of her vehicle in a disabled bay, or the situation was resolved. The real question is, if what she did was in fact on the level and part of an emergency situation, where are her priorities in devoting time to attempting to get the photo deleted? How could the picture matter?
It was a fine time and place, and it's good that Terence stood his ground and reminded an officer of both the limits of her power and the nature of the technology.
