Tip o' the hat to blamb for linkage to this report about mass arrests of Muslims in L.A. (ensuing discussion and supplementary linkage on MeFi). That's really freaking scary.
So's this, in a different way. (Thanks, digital ed.)
Also via MeFi comes a link to a good article (with its own supplementary linkage) about constraints that the workplace and the law may place on bloggers. (Yeah, I've rambled about this before -- go look in the archives if you're really interested.)
