I just watched it. Interesting discussion.
The one thing I would add: I've never been big on "one size fits all" and that includes believing all situations will always require waiting for the police to arrive and then decide if it's safe for them to enter. I've practiced clearing my home and anticipating vulnerabilities, advantages and likely trajectories, which I would know better than them.
