Whether or not there is a warrant is tangential to my argument. There used to be hard physical limits to the amount of surveillance that could be done. Now, the only limits are legal limits. Those legal limits were never designed to be the only limit, and are insufficient in their current form.
It's still illegal. I could go around keying people's car for potentially a lifetime without getting caught but it's still illegal and that's what we were talking about in the thread.
