US Justice Dept. defends warrantless cell phone tracking

The FBI and other police agencies don't need to obtain a search warrant to learn the locations of Americans' cell phones, the U.S. Department of Justice told a federal appeals court in Philadelphia on Friday.

A Justice Department attorney told the Third Circuit Court of Appeals that there is no constitutional problem with obtaining records from cellular providers that can reveal the approximate locations of handheld and mobile devices. (See CNET's previous article.)

The Internet has not transformed civic engagement... yet

Ars Technica reports on the new study The Internet and Civic Engagement which found that there is a strong correlation between income and political activity and that there is little difference between online and offline, except that online more people sign petitions. Looks like the Internet is not really broadening the social basis of political involvement.

The Big Sort

Another book for my reading list. Bill Bishop: The Big Sort: Why the Clustering of Like-Minded America Is Tearing Us Apart. 2008. http://www.thebigsort.com

The Wall Street Journal: 'Like-Minded, Living Nearby' (April 22, 2008)

The more diverse America becomes, the more homogeneous it becomes.

No, that's not a misprint; it is the thesis of "The Big Sort," Bill Bishop's rich and challenging book about the ways in which the citizens of this country have, in the past generation, rearranged themselves into discrete enclaves that have little to say to one another and little incentive to bother trying. "As Americans have moved over the past three decades," Mr. Bishop proclaims, "they have clustered in communities of sameness, among people with similar ways of life, beliefs and in the end, politics."

It is an idea that has all but obsessed Mr. Bishop since he began thinking about it years ago in his hometown of Austin, Texas. In his Austin neighborhood, he observed, there were virtually no Republicans. In another community of similar size nearby there were very few Democrats. Thirty years earlier, he was willing to bet, nothing like that uniformity would have been possible. Values, ideology and partisanship would have mingled more variously in even the most compact neighborhood, ward or district.
