Talking of terrorists, remember all the controversy back in 2009 when the US Department of Homeland Security listed domestic rightwing extremists and returning military veterans as among its top concerns when trying to keep of top of terrorism? I see no reason why that wouldn't be true in the USA as it has proved to be true in Europe. Since then we've had Breivik, of course, but also plenty of British nutters building bombs and setting them off, or threatening to do so. Now we've had an ex-Marine jailed for planting bombs which caused explosions in Dundee tenements.
Yet somehow it's Muslims we're all supposed to be terrified of. Aye, right. In your dreams.
