Government wants to read your tweets, Facebook posts

There is no harm in government reading what we write BUT the trouble starts when some people in the government uses these writings to harass its authors though the government will loose the same case in a court. for e.g. if you write against the maoist patriotic indians will support you but there are instances where the people employed to watch the site have leaked information to maoist telling them there is a guy here(on the site) who is against you. So, there should be checks and balances to protect innocents or atleast the government should do a background check on its own employees to prevent this kind of nonsense and harassment of the public.
