shines a light in our cracks.

Does "shines a light in our cracks" mean "reveals the flaws of our political system/our society"?

It’s appalling. Any doc (a urologist, dermatologist) can order a viral respiratory PCR panel, for instance, but an ID doc like myself can’t order a damn SARS-CoV-2 test, while S Korea is testing thousands of people a day. This epidemic really shines a light in our cracks.

Yes.

You're correct about it referring to flaws, but he's referring more to flaws in the medical system rather than political or societal flaws.

This actually isn't a joke on proctologists.

I wonder which is more accurate: "shines a light in our cracks" or "shines a light on our cracks"? The meaning of the two appears to be different. The former seems to mean "shines a light into the cracks" while the latter on the surface to reveal where the problems are.

I would prefer on there, but you understand what is meant, which is what is important.
