Where did the article indicate that Law Enforcement didn't need a warrant to access the Carrier IQ data?

I remember a time when they had to get a warrant before logging your information. Now with Carrier ID and Google and Facebook, the information is already collected, and they only need a warrant to access the years and years of detailed historical information. It's quite a big difference.

Carrier IQ isn't used by all carriers (Verizon opts out, I believe) and the data transmitted is anonymous. I admit there is a risk with the data profiles being assembled, and being done so with ease not seen before, but the carrier IQ findings seem to be bad tech reporting and fear mongering. It really seems to be "not a big deal".

I am all for advocating privacy and a discussion about user's rights -- but I would like it if both sides left their hysteria at the door.

anonymous data does not exist

whether or not they opt out, its detected on my vz device using the carrier iq detector app.

Carrier IQ is very much like wire tapping. Wire tapping requires a warrant[1]. What about warrant for Carrier IQ?

That was my point.

[1] Not sure, but I think it did at one point or still does. Maybe some bill or act made that void, not sure.
