    Keep in mind that all the cliches about black holes are about non-rotating black holes, which don’t exist in reality. In reality, a spinning black hole has a ring singularity, not a point, and behaves much weirder and even less intuitively than the hypothetical non-rotating counterpart as it smears out spacetime into taffy.

      Is it theoretically possible to shoot something through the ring? Or does the even horizon completely envelop it?

        The Black hole isn’t a ring, it’s a fuckin sphere, the ring surround it in it’s equator. Grinded material more and more acelerated until almost the speed of light nearby the hole, from where it falls into the hole to end as something nobody knows. Like the swirl formed when you take out the plug of the sink, but the hole in the middle is a sphere.

          The original comment were referring to the ring singularity which is different from the accretion disk.

          The singularity is unseen, we suppose it’s a ring in rotating back holes, but we have no idea. As anything inside the event horizon, we cannot see what’s going on in there.

          The accretion disk is the disk of matter falling into the black hole, it’s outside the event horizon and can be observed.

            Supposing the singularity as an unidimensional something what we don’t know. In any case we can’t see the black hole as such, but the gravitation it causes, form a sphere arround the singularity, visible as such by the accretion disk. If not, we only can observe an black hole by its influence, eg, the gravitation lense effect.
