Oh, stop with the histrionics. The person in your scenario went on to commit an actual crime. What was hers? Questioning an police officer? He brought it upon himself by being overly zealous; she overreacted, and it ended with a pregnant woman handcuffed on the ground. For an incident WHICH WAS NEVER A LEGITIMATE CRIME...which was the only point that I was trying to make in my post.
Histrionics? Perhaps taking the same mindset to its logical conclusion. She wasn't arrested for talking too loudly. Had the Me-ocrat suddenly learned that other people have rights, too, she would have said, "Gee, I didn't realize I was infringing on other people's rights. I'll try to do better. Thank you for informing me, Officer," and she wouldn't have been arrested.
Actually, enforcement of such scofflaws were what cleaned up NYC under Giuliani. It appears enforcement of such minor civil codes of conduct does have an effect.
