I am not uninformed, I watched the video. And again I don't know what particular tools these officers were working with. But I think we can do better as a whole in this country of prioritizing DV and learning to recognize risky situations, intervene, and empower victims. I'm not saying these officers could have or should have arrested then and there, but I do think there was a place for intervention beyond sending him to a hotel.
