Rather silly and incredible plot against the US Capitol busted as a man in Ohio is arrested in a Twitter sting, WJLA story here.
Update: Jan. 16
The New York Times has a front page story by Doreen Carnaval and Alan Cowell, "French rein in speech backing acts of terror: debate over fairness; Recent law allows for rapid trials and stiff prison sentences" here. Even shouting verbal support of attackers can lead to prosecution; this is not just about Internet speech. The NTY points out that this sounds like a paradox.
