What I can’t understand is why they entered the house after that interaction and the video I saw didn’t show.
To my knowledge, there was no reason or justification given. Grayson had turned off his body cam, and his partner had walked away to get the license plate of the car in the driveway. Grayson followed her into her home asking for ID. She seemed confused and scattered through the whole encounter. She might have been intoxicated or on medication. She might have had mental health problems. She may have even been using illegal drugs. But none of that is a crime if you’re in your own home not bothering anyone. IMO, they were fishing for a reason to treat her as a suspect.
This video has a good breakdown with footage from both officers’ body cams: youtu.be/7jP3FGj7syI
