internet - The so-called suicide of a teacher

Pictures and statements of demonstrating students in Rui'an, including video of clashes with armed police have hit the internet, here summerized by ESWN.
The students have been calling for justice in this rather extraordinary protest after one of their teachers, Dai Haijing, committed suicide according to the police.
The students suggest their has been a cover-up. Up to 10,000 people have attended their protests.

Update: Global Voices suggests a task force is needed to save the video clips made from protests like this one. Chinese hosts move very fast to delete this kind of video's when ordered so and unlike other online tools, it is very hard to save them.
