True. But the other park employee or officer, the woman, had a completely different take on the situation, and was vocal about it, repeatedly. She had a long talk with Gabby about her relationship seeming "toxic", and she turned out to be right. If she could be that insightful, others could learn to be, too. She also pointed out to the other officers, that BL wasn't the only one with marks on his face.
But you're right; it's easy to critique from the peanut gallery. When you're in the middle of a highly emotional scene, and are receiving some mixed signals from the parties involved (minimizing the situation (when not crying hysterically), claiming they're engaged (which they no longer were) & in love, etc.), it's a lot of messy stuff to wade through and make sense of.
Still, I'll be interested to hear how the PD's review of the handling of the situation goes.
