An expanded tool for law enforcement — increased access to Skype

Changes in technology are now making it easier for law enforcement to eavesdrop — with a court order — on Skype chats, though not on audio and video calls.  

This Washington Post article gives the details on expanded access by law enforcement to chats and user data, as well as some of the privacy issues.  According to the article, surveillance of the audio and video feeds still isn’t practical. I wonder how long it will take for that to change.

How will your fictional law enforcement officers use this expanded access? How will your other characters — and not just the bad guys —  respond?
