President Obama, who ought to know better, given the grief he gets for his skin color and his overseas family connections, thinks this kind of warrantless search is just fine:
The federal appeals court based in Washington D.C. said in August that investigators must obtain a warrant for GPS in tossing out the conviction and life sentence of Antoine Jones, a nightclub owner convicted of operating a cocaine distribution ring. That court concluded that the accumulation of four-weeks worth of data collected from a GPS on Jones' Jeep amounted to a government "search" that required a search warrant.
Judge Douglas Ginsburg said watching Jones' Jeep for an entire month rather than trailing him on one trip made all the difference between surveilling a suspect on public property and a search needing court approval....
The Obama administration last month asked the D.C. federal appeals court to change its ruling, calling the decision "vague and unworkable" and arguing that investigators will lose access to a tool they now use "with great frequency" [Pual Elias, "Discovery of GPS Tracker Becomes Privacy Issue," AP via Yahoo News, 2010.10.16]
Think about it, Mr. President. You have teabaggers making the nutty claim that they are engaged in a noble crusade against a tyrannical government. If you're going to support warrantless GPS tracking, you make it that much harder to refute claims that Big Brother is in charge.
Of course, I'm still waiting for the teabaggers to get off Marxism and tackle the real tyranny in our midst.
