This is terrible, horrible stuff. This is exactly what so many have feared; a database held by an unaccountable central government group that can identify your address based on your social media and cell phone traffic. Your local police don't even have this information, because to have this is an invasion of your privacy and your freedoms. This is the exact opposite of "sit under their own vine and fig tree and no one shall make them afraid". We all should be very, very afraid of this, and we need to seriously vote this out of existence as fast as possible. This is a call to action, and no I am not being a Cassandra here; the sky is starting to fall.
