As ChinaÂ’s legislature prepared to elect a new president and prime minister this week, security in Beijing was raised to a high level. Security forces and plainclothes officers were stationed at intersections around the city with numerous squad cars and police vans nearby. China has experienced sporadic worker protests, and in late February, bombings at two prominent universities. Authorities announced the arrest of a man they consider solely responsible for the bombings, but the general public greeted the news with skepticism.
