Re: It is our job to uphold the law
If I'm mugged at gunpoint, that's a crime in progress, but I'll be handing over my wallet all the same. If a child is kidnapped in practice you find that often people do what the criminals want first, then go to the police only afterwards.
Comparing on the one hand, paying an extortionist to retrieve irreplaceable property, and on the other, being too idle to shout "Oi!" at a casual thief, is just silly. They are different.
