"The dog... was shot and killed during an 'Interaction'" is such an outlandishly vague way to describe the situation and leaves all details up to the imagination. It doesn't even say if that interaction was with their suspect. A suspect who "is injured" but like, did they injure the guy or did they injure themselves? Did they get shot too? Did the dog try to attack them and was shot by the suspect? Did the dog run at them, and a cop shot at the same time, killing the dog instead of maiming the suspect?

Cops always use passive language so it sounds like all this violence was already there when they showed up.
