Many worldwide governments are trying to pass a new law to allow them to watch emails, texts and calls. First of all let me point something out any government with the proper resources could do this without you knowing anyway and just makes this law pointless because if they are going to watch you then they will find a way.
Months ago governments wanted to pass two laws that were identical to CISPA, these laws were called PIPA and SOPA. In a practical world these laws would never pass because it breaches human rights, anyone has the right to keep things private and this includes emails, texts and calls.
If it becomes a legal requirement to hand out access to this information then the human right laws are pointless. I doubt CISPA would pass and if it does we might as well hand over everything to our local governments because from this point it means you have no privacy or freedom.
