That would be nothing for them

[suprunp]

“You think they might just handle it themselves without making anything public?”
“That would be nothing for them. We’ll know what happened when we see tomorrow’s newspaper—whether they reported the death or not. I’m no gambler, but if I had to make a bet, I’d put my money on their not reporting it.”
(H. Murakami; 1Q84)

What exactly is it supposed to mean?

Does it meant that it would be nothing (easy) for them to handle it themselves?

Thanks.

More context is needed to be certain, but I think you're right.

Yes, you have the right idea.

That would be nothing for them = that would not be a challenge for them to handle it. or that would not be an issue to them.

It doesn't mean just easy for them to do, it implies this is their de facto behavoir. The "nothing" implies they are doing "nothing outside of their normal MO", i.e. nothing "unusual".
