water cannon, tear gas, stun baton....and more experiences dealing with mass incidents

hopefully we learned lessons:

1. never have a leader like zhao zy again.

2. highly alert on mass demonstration. even if it starts peacefully, large assembly of people tends to create chaos, esp if it's politically motivated and considering chinese civilization level.

can any1 believes the tragedy just happened in duisburg, germany, one of the most organized, civilized nations (besides japan in my view) in this world
