Harkin

Harkin was one of the first human officers of C-Sec who Captain Anderson calls "a disgrace to the species." During his 29 years in C-Sec, he was guilty of roughing up suspects in custody, bribery accusations, and alcohol and drug use. The embassy used to step in when he got in trouble, for fear that it would look bad on the human race if he got fired. Now there are enough humans in C-Sec to stop protecting him, so he was fired for drinking on the job.
