Define "Reasonable."

The Obama Justice Department has argued that you have no reasonable expectation of privacy with regards to your own personal whereabouts.

This is just one more reason I have always refused to have a cell phone. I saw this coming back in the day when phones didn't yet have GPS transceivers in them. If for some unforeseen reason I end up carrying a mobile phone, it's going to live in an aluminum box when I am not calling someone. Incoming calls will be missed, and nobody's a-trackin' me, thanks.

You have EVERY right to expect that your location will be private. That it makes the Only Ones' job harder in a rare circumstance is not an excuse to oppress most of the people in the WORLD! Infringing your right to privacy has no end once begun. So what, if it makes law enforcement easier. You know what else would make law enforcement easier? A DNA, fingerprint, retina scan, and blood storage database, collected at birth. That could be tied to a GPS tracking device implanted in all newborn children after passage of the law requiring it. Existing people would be FELONS if they didn't get the implant. The Only Ones could know where everyone is, at all times, and have a way to positively identify everyone. Do you object to that idea? What's the difference, besides scale of intrusiveness?

Where is the cutoff point?

The worse question is, who decides?
