Where is Freedom of Speech and Expression??

The Preamble of the Indian Constitution ensures to all its citizens the liberty of expression.
Article 19(1)(a) of Indian Constitution says that all citizens have the right to freedom of speech and expression. Freedom of Speech and expression means the right to express one's own convictions and opinions freely by words of mouth, writing, printing, pictures or any other mode. It thus includes the expression of one's idea through any communicable medium or visible representation, such as gesture, signs, and the like. This expression connotes also publication and thus the freedom of press is included in this category. Free propagation of ideas is the necessary objective and this may be done on the platform or through the press. This propagation of ideas is secured by freedom of circulation. Liberty of circulation is essential to that freedom as the liberty of publication. Indeed, without circulation the publication would be of little value. The freedom of speech and expression includes liberty to propagate not one's views only. It also includes the right to propagate or publish the views of other people; otherwise this freedom would not include the freedom of press.
Freedom of expression has four broad special purposes to serve:
1) It helps an individual to attain self-fulfillment.
2) It assists in the discovery of truth.
3) It strengthens the capacity of an individual in participating in decision-making.
4) It provides a mechanism by which it would be possible to establish a reasonable balance between stability and social change.
5) All members of society would be able to form their own beliefs and communicate them freely to others.  
But presently what is happening in India? Shutting the mouth of Democracy?
Where are we moving towards?
I was shocked to listen to the news that some of the netizens were arrested for expressing their views or sharing something about someone.
Definitely this is cutting the tongue of Indian Citizens.
