Surveillance and wiretapping are not the same thing

A lot of the apologists for the database debacle have been quick to point out that the NSA isn't wiretapping domestic calls. But that doesn't mean what they're doing isn't surveillance. Just in case there are any doubts, let's review the definitions. From dictionary.com:

Surveillance: "Close observation of a person or group, especially one under suspicion."

Wiretapping: "A concealed listening or recording device connected to a communications circuit."

I certainly don't want the government listening to my calls. But I don't want them surveilling me either. Do you?
