They can send the police, sure. Doesn't mean I have to answer their questions.
This is a somewhat absurd argument because what I'd do ultimately depends on the circumstance. If I truly know nothing besides my own name and that I found this person bleeding, I would be wondering where my other memories went and if I were brain damaged.
In the general case, they aren't going to be sending detectives immediately to ask questions because someone called 911. Nor would I stay on the scene longer than I was medically needed to be there. But the "general case" is a useless fiction.
