A police training

The China Digital Times comes with interesting pictures of a "mass incident" at Changchun. To kill right away all possible rumor: it is a live training by the police, not a real incident.
That in itself is good news. We have seen in the past few years so many pictures of real mass incidents where the police did not seem to have a clue what to do. When it becomes routine for police forces to be prepared for these inevitable incidents, that can only help to limit the damage.
