Police and protesters scuffled in Edinburgh ahead of Wednesday's G8 summit as officials braced for more demonstrations and the possibility of a terrorist attack. Helmeted police and officers on horseback stopped a march by about 300 black-clad anarchists and antiglobalization protesters as helicopters circled overhead Monday. In a second standoff in Scotland's medieval capital, riot police stood three-deep to stop a mix of about 150 anarchists, clowns and local people, The Associated Press reported.
