The multilateral summits are happy hunting grounds for protesters with a thousand causes to peddle. This time round, Manmohan Singh was spared the mandatory sloganeering by Kashmiri protesters and Khalistan activists that greet him every time he is in the US. But Chinese President Hu Jintao had no such luck. Along one route to the Washington Convention Center, the heavily-guarded venue of the 47-nation Nuclear Security Summit that ended Tuesday, one could see scores of followers of the outlawed Falun Gong cult dressed in canary yellow jackets shouting: “Hu Jintao is killer. Stop Genocide.” There were also a smattering of Tibetan protesters lining up the route to the convention centre.
