And they would have said, “We can’t do anything. No law has been broken”.

You are wrong. A law was broken. He was a felon in possession of a firearm. And it was a stolen firearm.

But you miss the point entirely. Even if the police did not do one thing .. I would have done what I could. I don't care if ten people behave irresponsibly ..so long as I do the right thing. Now do you get it?

Hindsight is easy. I don’t believe it’s likely that you can surmise what you “would have done” “if you had been there”.
