Yes, I think US law is different to UK law in many ways.
As you say, in the US if someone refuses to assist police enquiries
then there could be a charge of obstruction. But not if the police
don't contact them.

But there is still the moral question of whether not giving the
information voluntarily to the police is protecting a murderer or
rapist from being stopped from committing more crimes and harming
innocent people.
