you are right,
but the question is:
where we must seek the dark mater?

in supermassive black holes, in galactic halos, in intergalactic gas…?

some weeks ago was described here:

http://www.sciencedaily.com/releases/2006/08/060821133930.htm

how the collision of two galaxy clusters can be interpreted as direct proof for the existence and some characteristics of the dark matter.

We will not can see so direct the dark matter in black holes,
just as we may not see baryonic matter in it,

but it would be fine, we had a theoretical model,
whether and how much dm is behind the horizon
