These globular clusters have always seemed peculiar to me. One would surmise that such a structure would result in a massive black hole without the rotational effects of say a galaxy.
Spiral galaxies tend to have regular rotation, but elliptical galaxies are much more like a globular cluster, although globular clusters aren't thought to contain dark matter. It's just a lot of stars going round in random orbits. They would have to lose angular momentum in order to collapse into the centre. They can get stripped, however, by tidal gravitational effects.
