Isn't this whole debate out of context? The way that I understand this is that they get a warrant to wiretap a person rather than a number. They then do not have to get another warrant each time that person changes phones. Am I wrong?
If I am correct, these are not really warrant-less wiretaps. They are taps without a warrant on a specific number. Necessary to track any bad guy these days. I am a conservative who believes we should pick our fights wisely. This might be one to leave alone.
