Blogging : Is it the right place to express our thoughts openly?

Now a days blogging is becoming very popular and mostly many people have started blogging today. But the main problem is how far this blogging world is giving freedom to write and to express our thoughts to this outside world. I don't know about other countries, but I am ready to talk about India. Here in India the freedom to write and the freedom to speak is really less. If we start to write any thing bad about politicians or some other thing means, then by the next second itself police will come and catch us regardless of not knowing any thing. This is the reason why many people are not interested to talk about the national issues here in India. Even though if we talk there is no use, that is secondary case. My point is if there is no freedom to do the thing whatever we like means, then what's the use of living in a country. So from this the politicians are concluding that "We will do whatever we like and we don't want any one to criticize us".

Recent issue : In India one boy wrote in his blog that "I hate these so and so poli***ns". Then using the IP address the police tracked him and he is arrested.

This is the reason i put this post here. You people just tell whether blogging is really the right media to express our thoughts openly to this outside world.
