Avoid tear gas
The latest protest tool: 'texting':
For protesters navigating Manhattan during the Republican National Convention, text-message broadcasting services like this, sent to their cell phones, provided an up-to-the-minute guide to the action on the streets.
Texting "tells you where the hot zones are, where people are getting arrested," said Greg Altman, 31, of New York City. "It tells you which stuff to avoid." When he got a message Tuesday that protesters were being beaten near Manhattan's Union Square, he stayed away.
Protesters weren't just employing the message services to look for trouble and stay out of it.
