Most of what's being criticized among the NYPD's tactics against RNC protestors is genuinely questionable behavior, such as entering protestors' meetings by lying to the organizers. I only would caution civil libertarians to be careful of what they label as "spying," and not include monitoring of publicly visible behavior in that category.
There was a tradition of soap-box public speaking in Sator Square. "Speaking" was stretching a point to cover the ranters, haranguers and occasional self-absorbed mumblers that spaced themselves at intervals amongst the crowds. And, traditionally, people said whatever was on their minds and at the top of their voices. The Patrician, it was said, looked kindly on the custom. He did. And very closely, too.

Angua brushed out her hair in front of the mirror.
"I don't like this," said Carrot. "It's not a proper way to behave."
She patted him on the shoulder. "Don't worry," she said. "Vimes explained it all. You're acting as though we're doing something wrong."
"I like being a watchman," said Carrot, still in the mournful depths. "And you've got to wear a uniform. If you don't wear a uniform it's like spying on people. He knows I think that."
Angua looked at his short red hair and honest ears. [...]
"And I've never worn plainclothes."
"On you they'll never be very plain," said Angua, pulling on her coat. It was a relief to be out of that armor. As for Carrot, there was no disguising him. The size, the ears, the red hair, the expression of muscular good-naturedness...
