So you suggest promoting females based on sex versus being qualified? The females in HPD are well represented and are promoted based on qualifications up to the rank of Lieutenant.  From Captain on, they are hand picked.  The lack of females at the top is due to the lack of females in the department, as a whole. Each rank has a term of service, usually 2 yrs. with a degree and 4 years without, that must be fulfilled before you can promote to the next rank, except the rank of Deputy Chief.
