It's not "surveillance data," you are in a public place and have no expectation of privacy. It's only through such neighbourhood watch and open-source intelligence initiatives that our communities can be kept safe from criminals and terrorists.
Why are you so protective of your goings-on and the names of everyone you call? Are you calling terrorists or engaging in illicit activity at the places you visit? What is it that you have to hide?
I would actually take the premise of (national) security even further and extend collection to not only metadata, but data as well. Further, these capabilities should be open-sourced and made available to all private citizens. Our current law enforcement systems are not powerful enough, nor do they move quickly enough to catch criminals - by the time sufficient information has been gathered on a suspect, it may already be too late.
