You both make excellent points. And it's not just a problem on CSI:Miami, either: writers for today's TV shows and movies are terrible at writing female characters. They all resort to clichés and stereotypes that apply to very few women in real life. It's truly sad how sexism is still so pervasive 30-50 years after Second Wave feminism. The only difference is that it's less overt and more subtle- you're less likely to hear a male character say "She's a woman, so she can't do this on her own". Instead, a female character is never shown doing something on her own without the assistance of a male character- it implies rather than outright declares "Women can't do stuff without men". But the message is still the same.
