Implement cyber laws

Dear Editor,
It is a matter of grave concern that some people have been abusing social/ electronic media. They are largely responsible for pushing India backwards from 133 in 2016 to 136 in 2017 to 138 in this year in World Press Freedom Index.
Some of those who use social media can go to the extreme of celebrating a brutal killing of a courageous lady editor, Gouri Lankesh! They can spit unprintable filthy abuse whenever an opinion does not tally with their own. Social media has even been made a place for uploading caste/ gender atrocities to create a reign of terror. Even it is now being used to manufacture a riot or to lynch people after giving them a bad name like child lifters etc.!
The need of the hour is to strictly implement cybercrime laws.
