Dear Health,
All the reports are that he told officers he was carrying a knife. It is noticeable (to me) in the video. I am confused why it is not reported as he had a knife. Unless it means he threatened them with the knife. It is unclear.
It does not seem like the police had enough time to do much evaluation here.
Was the knife the issue? (See above.) How do you know they told him to drop the knife? Why is holding a knife such a big deal? I have a knife right now. Don’t shoot.
