I also believe that beating people is inhuman activities and this should be condemned. But we need to see the flip side of the coin too.

let us analyze what is peaceful demonstration. Is blocking the road, burning tyre on the street, obstructing to enter the UN or any other premises can be called as a peaceful demonstration? Did you people in the US enjoy these things during the April uprising?

So far in my knowledge, in US you have to get a written permission from the competent authority to make a demonstration explaining nos. of people, types of banner and slogan, routes and places.Eventhough U are not allowed to completely obstruct the road, possibly a lane.

I do believe that there are a lot of Tibetan refugees in US and why didn't they obstruct the road, burn tyres on the street and did not demonstrate in front of UN headquarters by completely obstructing the entrance and exit.

Try to do it in the US and see the response of the police.

So what alternatives police has to disperse the crowd when they failed to comply with the lawful order. Police are not  benefitted by beating people personnaly.
