From the Huffington Post:
U.S. law enforcement appears to be reading from a playbook perfected in the streets of Tehran. In the wake of protests last week at the G20 meeting in Pittsburgh, the police arrested a self-professed anarchist for using the social-networking site Twitter to coordinate communications among G20 summit protesters, and direct them away from police positions. The charge for this exercise of free speech: the criminal uses of a communications facility, in this case a computer and a Twitter feed. . .
. . . The next time protestors take to the streets of Tehran or Beijing, armed with cell phones and Twitter accounts, we should not be surprised when countries crack down hard on those tweeting the revolution and point to Pittsburgh as a precedent. And America will be relegated to the sidelines, rendered mute by our own foolish actions.
