Well, if there was a reason to move, maybe construction, or a bike race or something, I would say "are we in the way of something?" or something along those lines. Most do remember who they work for, and respect that. My father does. My grandfather did. All the people they worked for did. I knew those people, know the policemen, and it is there job to protect the public. If the old women in particular were in risk of a construction accident, like a falling tool (it HAS happened before) it would be worse to stand and do nothing.
Once again I fight the lie that all police are crimials with a badge. Really it is a lie told by the mass media, and apperantly all you believe it. Probably most of you don't know a police officer, or anything.
But enough of my rambling.
