  We estimate the number of individual, fast-moving stars observable in
globular clusters under the assumption that the clusters contain massive
central black holes which follow the galactic black-hole mass vs. sigma
relationship. We find that radial velocity measurements are unlikely to detect
such stars, but that proper motion studies could reveal such stars, if they
exist, in the most likely clusters. Thus, HST proper motion studies can test
this hypothesis in a few nearby clusters.
