Garibaldi: Early on I could take him or leave him. I think that he doesn't serve much of a function at first because in literally the first three stories it's always Jeff sneaking up on the bad guy and getting into a firefight, when that seems more like the job of a security chief.
Really? Honestly, I always thought it was a little strange in Star Trek that the security chief was always leading teams personally. I mean, how many raids does a chief of police lead in real life? Their job's to manage, direct, and organize responses to everything that might be happening at a given time, and they can't do that as well out at the front of a specific team on a specific incident.
