can the police order you back into your own house, when they're arresting someone across the street?

Here’s the thing. Cops have to both worry if you are going to be a threat to them AND if you are endangered. If a cop tells meto go back inside, I’m going to do it. Not because they have the “right” to order me to. They probably don’t. But because there could be bullets flying around.

And you don’t know this?
