Would you really trust them in an emergency? Be honest. I know that my answer would usually be no. In most cases they are glorified secretaries in uniform. They do keep a sense of order in general just by their presence, but if a situation got dangerous I would not feel safe putting my life in their hands.
For example: Last week I had to hand-deliver a package across the street to the MLB offices. After talking with a woman at the front desk, I was told to go around the corner to the messenger entrance where someone would come out and escort me upstairs.
When I approached the door that I supposed to be the messenger entrance, I peeked through the little window at the top and what did I see? I saw four women in uniform gyrating, dancing, and laughing hysterically in a small office. Inspirational, no? After I entered and the women were suitably embarrassed, I met one of them around the corner and we entered the elevator together.
Woman: It's not what you think it was. We were doing our impressions of that Nextel commercial.
Me (playing along): That's exactly what I thought it was.
Woman: Don't you just love that commercial, it is so funny!
Me: So, what residential college are you in?
And these are the people protecting our buildings?
